AP133
300mA, LOW QUIESCENT CURRENT, FAST TRANSIENT
LOW DROPOUT LINEAR REGULATOR
Description
Features
The AP133 is a 300mA, adjustable output voltage, low dropout
linear regulator. The device included 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.

300mA Low Dropout Regulator with EN
Very low IQ: 40µA
Wide input voltage range: 2V – 6V
Adjustable output: 1V – 5V
High PSRR: 65dB at 1kHz
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 40μA from zero to maximum load.
Ultra-fast start-up time: 25µs
Stable with low ESR, 1µF ceramic output capacitor
Excellent Load/Line Transient Response
Low dropout: 350mV at 300mA
Current limit protection
Built-in current-limit and thermal-shutdown functions prevent IC
from damage in fault conditions.
Short circuit protection
The AP133 is available in SOT25 and DFN2020-6 (preview)
package.
Thermal shutdown protection
Ambient temperature range: -40ºC to 85°C
SOT25 and DFN2020-6 (Preview): Available in
“Green” Molding Compound (No Br, Sb)
