V OUT =5.V at 3mA Maximum Input Voltage: 8V Guaranteed output current: 3mA Low quiescent current: 4A (typ. Current limiting Over-temperature shutdown SOT23 SOT23-5 SOT89 TO92 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 (4A typ. with low dropout voltage making them ideal for battery applications. The space-saving SOT23 package is attractive for Pocket and Hand Held applications. The devices are capable of supplying 3mA of output current continuously. They are available with several fixed output voltages ranging from 1.8V to 5.V. 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.

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. Rev September 3 28
