The AP133 is a 300mA, adjustable output voltage, low dropout
linear regulator. The device includes pass element, error
amplifier, band-gap, current limit and thermal shutdown circuitry.
The device is turned on when EN pin is set to logic high level.
The characteristics of low dropout voltage and less quiescent
current make it good for low power applications, for example,
battery powered devices. The typical quiescent current is
approximately 40
μA from zero to maximum load.
Built-in current-limit and thermal-shutdown functions prevent
IC from damage in fault conditions.
The AP133 is available in SOT25 and DFN2020-6 packages.
