Description

The APL5501, APL5502, APL5503 are micropower, low noise, low drop out linear regulators. Operate from 2.7V to 6V input voltage and deliver up to 500mA. Typical output noise is just 50mV RMS with the addition of an external 0.1mF bypass capacitor in BP pin and  typical dropout  voltage  is  only  170mV at  500mA loading. Designed for use in battery-powered system, the low 50mA quiescent current makes it an ideal choice.

Features

1. Low Noise : 50mVRMS (100Hz to 100kHz)

2. Low Quiescent Current : 50mA (No load)

3. Low Dropout Voltage : 170mV (@500mA)

4. Very Low Shutdown Current : < 0.5mA

5. Fixed Output Voltage : 1.3V ~ 3.4V

6. Stable with 4.7mF Output Capacitor

 

Applications:

1. Notebook Computer

2. PDA or Portable Equipments

3. Noise-Sensitive Instrumentation Systems

Description

The L5985 is a step-down switching regulator with a 2.5 A (min.) current limited embedded
Power MOSFET, so it is able to deliver up to 2 A DC current to the load depending on the
application condition.The input voltage can range from 2.9 V to 18 V, while the output voltage can be set starting from 0.6 V to VIN .

Having a minimum input voltage of 2.9 V, the device is suitable for a 3.3 V bus.Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator thatcan be externally adjusted up to 1 MHz.

Features

1. 2 A DC output current

2. 2.9 V to 18 V input voltage

3. Output voltage adjustable from 0.6 V

4. 250 kHz switching frequency, programmable up to 1 MHz

5. Internal soft-start and inhibit

6. Low dropout operation: 100% duty cycle

7. Voltage feedforward

8. Zero load current operation

9. Overcurrent and thermal protection

Applications:
