1 300mA TinyPower TM LDO Features Output voltage ranges: Fixed range of 1.8V 2.5V 2.7V 3.0V 3.3V 5.0V type. Highly accuracy: 2% Low voltage drop: 240mV (typ.) V OUT =5.0V at 300mA Maximum Input Voltage: 8V Guaranteed output current: 300mA Low quiescent current: 5A (typ.) Current limiting Over-temperature shutdown SOT-23 SOT-89 TO-92 Packages Applications Portable electronics PC peripherals Wireless devices Battery powered devices Cordless phones Electronic scales General Description The HT72XX series of positive linear regulators features low quiescent current (5A typ.) with low dropout voltage making them ideal for battery applications. The space-saving SOT-23 package is attractive for Pocket and Hand Held applications. The devices are capable of supplying 300mA of output current continuously. They are available with several fixed output voltages ranging from 1.8V to 5.0V. Although designed primarily as fixed voltage regulators these devices can be used with external components to obtain variable voltages and currents. These rugged devices have Thermal Shutdown and Current Limiting to prevent device failure under the Worst of operating conditions.

Stresses exceeding the range specified under Absolute Maximum Ratings may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability. * Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional but do not guarantee specific performance limits.

Load regulation is measured at a constant junction temperature using pulse testing with a low ON time and is guaranteed up to the maximum power dissipation. Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. The maximum allowable power dissipation at any ambient temperature is P D =(T J(MAX) Ta) / JA. 2. Dropout voltage is defined as the input voltage minus the output voltage that produces a 2% change in the output voltage from the value at V IN =V OUT 1V with a fixed load. 3. Current limit is measured by pulsing for a short time.
