Description
The STLQ50 is a BiCMOS linear regulator
specifically designed for operating in
environments where very low power consumption
is required.
Its very low quiescent current (3 µA) results in
extended battery life, making the device suitable
for applications which have very long standby
time.
The PMOS pass element allows very good
dropout values (200 mV at 25 mA I
O
and 350 mV
at full load) without affecting the consumption
characteristics.
Housed in the very small SOT323-5L, it meets
space-saving requirements in battery-powered
equipment.
