1 Advanced Monolithic Systems FEATURES Fixed and Adjustable Versions Available Output Current up to Very Low Reverse Battery Protection Input-output Differential less than.6v Short Circuit Protection Internal Thermal Overload Protection Load Dump Protection Overvoltage Protection Mirror Image Insertion Protection ON/OFF Pin AMS7 LOW DROPOUT VOLTAGE REGULATOR APPLICATIONS Cellular Telephones Portable Consumer Equipment Portable (Notebook) Computers Battery Powered Systems Portable Instrumentation Radio Control Systems CD/DVD drives Automotive RoHS compliant GENERAL DESCRIPTION The AMS7 series consists of positive fixed and adjustable voltage regulators ideally suited for use in battery-powered systems. These devices feature very low quiescent current of.8 or less when supplying loads. This unique characteristic and the extremely low input-output differential required for proper regulation (.V for output currents of ) make the AMS7 ideal to use for standby power systems. Internal circuitry of AMS7 is protected from input fault conditions caused by reverse battery installation or input voltages that exceed maximum rated input voltage. During line transients, such as load dump (V) when the input voltage to the regulator can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both internal circuits and the load. The AMS7 series also includes internal current limiting, thermal shutdown, and is able to withstand temporary power-up with mirror-image insertion. The AMS7 is offered in lead TO-9, 8 lead SOIC, SOT-89, SOT- and TO- packages. ORDERING INFORMATION OUTPUT PACKAGE TYPE TEMP.

For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. Note : To ensure constant junction temperature, low duty cycle pulse testing is used. Note : Limits appearing in boldface type apply over the entire junction temperature range for operation. Limits appearing in normal type apply for T A = T J = C. Note : The maximum allowable power dissipation is a function of the maximum junction temperature T J(MAX), the junction-to ambient thermal resistance θ J-A and the ambient temperature TA. The maximum allowable power dissipation at any ambient temperature is calculated using: P(MAX) = T J(MAX) - TA θj - A Where the value of the junction-to-ambient thermal resistance are as follows: 9 C/W for TO-9 (N), 6 C/W for the SO-8 (S), C/W for SOT-89 (L), 9 C/W for SOT- and 8 C/W for TO-.

Measured when the output voltage has dropped from the nominal voltage obtained at V input, dropout voltage is dependent upon load current and junction temperature. Input Voltage: The DC voltage applied to the input terminal with respect to ground. Input-Output Differential: The voltage difference between the unregulated input voltage and the regulated output voltage for which the regulator will regulate. Line Regulation: The change in output voltage for a change in the input voltage. The line regulation is measured under conditions of low dissipation or by using low duty cycle pulse testing such that the average chip temperature is not significantly affected. Load Regulation: The change in output voltage for a change in load current at constant chip temperature. Long term stability: Output voltage stability under accelerated life-test conditions after hours with maximum rated voltage and junction temperature. Output Noise Voltage: The rms AC voltage at the output, with constant load and no input ripple, measured over a specified frequency range. : That part of the positive input current that does not contribute to the positive load current. The regulator ground lead current. Ripple Rejection: The ratio of the peak-to peak input ripple voltage to the peak-to-peak output ripple voltage at specified frequency. Temperature Stability of V O : The percentage change in output voltage for a thermal variation from room temperature to either temperature extreme. External capacitor The AMS7 series require an output capacitor of µf or greater to ensure device stability. Without the capacitor the device may oscillate. Most type of tantalum or electrolytic capacitor can be used in the applications. A critical characteristic of the capacitors is an ESR value of Ω or less and a resonant frequency above khz. The value of this capacitor can be increased without limits. For higher loads, the value of the capacitor should be increased, specialy when the output voltage is set for.v or less. The AMS7 lowest fixed output voltage value is.v. Typical application circuit (adjustable output) µf Minimum Load k OUT OFF ON/OFF AMS7 ADJUSTABLE R 8k ON ADJ + GND V IN R C µf V OUT In circuits using the fixed output voltage versions, minimum load is not required. For circuits using the adjustable device, the value of R and R should be chosen such, that a current of approximately µa flows through the network. The reference voltage (.V) is measured between the adjust pin and V OUT. The output voltage can be set by the two resistors R and R using the following equation: V O = V REF R + R R The value of R is recommended to be between kω to kω, and the value of R will set the output voltage. updated April, 9
