Temperature Range

The usual PNP pass transistor has been replaced by

a PMOS pass element. Because the PMOS pass

element behaves as a low-value resistor, the LDO

voltage, typically 415 mV at 50 mA of load current, is

directly proportional to the load current. The low

quiescent current (3.2

µA typ) is stable over the

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.
