FEATURES
DESCRIPTION
The SC5205 is a 150mA ultra low dropout linear
regulator with a built in CMOS/TTL logic level enable
switch, designed specifically for battery powered
applications where low quiescent current and low
dropout are critical for battery longevity.
The SC5205 uses a Semtech proprietary internal
PNP device for the pass element, providing a low
dropout voltage of 165mV at a load of 150mA, while
maintaining a ground pin current of 2750A.
The output noise is reduced by placing a 10nF
capacitor on pin 4 (bypass).
Each device contains a bandgap reference, error
amplifier, PNP pass element, thermal and current
limiting circuitry and resistor divider network for setting
output voltage.
The SC5205 is packaged in a 5 pin SOT-23 surface
mount package for a very small footprint and it
requires only a 1F capacitor on the output for a
minimum amount of external components.
