LESHAN RADIO COMPANY, LTD. L R75XX 100mA CMOS Low Power LDO Features High output current : 100mA (Pd ≤ 250mW) Output voltage accuracy: tolerance±3% TO-92, SOT-89 and SOT-25 package Low power consumption Low voltage drop Low temperature coefficient High input voltage (up to 24V) Applications Battery-powered equipment Communication equipment Audio/Video equipment General Description The LR75XX- 1 series is a set of three-terminal high current low voltage regulator implemented in CMOS technology. They can deliver 100mA output current and allow an input voltage as high as 24V. They are available with several fixed output voltages ranging from 3.0V to 5.0V. CMOS technology ensures low voltage drop and low quiescent current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents.
