UM165xx
300mA, Micropower, VLDO Linear Regulator
UM165xx SOT23-3
General Description
The UM165xx series are VLDO (very low dropout) linear regulators designed for low power portable applications.
Maximum dropout is just 90mV at the load current of 150mA.
The internal P-channel
MOSFET pass transistor requires no base current, allowing the device to draw only 100μA during normal operation at the maximum load current of 300mA.
Other features include high output
voltage accuracy, excellent transient response, under
voltage lockout, stability with ultralow ESR ceramic
capacitors as small as 1μF, reverse-battery protection, short-circuit and thermal overload protection and output current limiting...
