SHUTDOWN
General Description
• Input Voltage Range is up 2.7 to 5.5V
• Dropout Voltage 400mV at 300mA Output Current
• Guaranteed 300mA Output Current
• Internal Ron = 1.5Ω PMOS draws no Base Current
• Low Quiescent Current 50µA
• Output Voltage: 1.5V/1.8V/2.0V/2.5V/2.8V/3.0V/3.3V/
3.5V; Accuracy 2%
• Active Low Shutdown Function (EN pin)
• Fast Transient Response
• Good Load Regulation
• Current Limit and Thermal Shutdown Protection
• Short Circuit Current Fold-Back
• Lead-Free and Green Package: SOT89-5L is
available in Lead-Free only. SOT25 is available in both
Lead-Free and Green (Note 1).
The AP131 is a 300mA, fixed output voltage, low dropout linear
regulator. The Device included pass element, error amplifier,
band-gap, current limit and thermal shutdown circuitry. The
device is ON when the EN pin is set to logic high level.
The characteristics of low dropout voltage and less quiescent
current make it good for some critical current applications, for
example, some battery powered devices. The typical quiescent
current is approximately 50µA from zero to maximum load. Due
to the internal flexible design, it results in extensively fixed output
voltage versions and makes it convenient to use for applications.
Built-in current-limit and thermal- shutdown functions prevent any
fault condition from IC damage. An external capacitor can be
connected to the BP pin and reduce the output noise.
