AS1363

500mA, Low-Dropout Linear Voltage Regulator

1 General Description

2 Key Features

ꢀ Guaranteed Output Current: 500mA

The AS1363 is a low-dropout linear regulator that oper-

ates from a +2.0V to +5.5V supply and delivers a guar-

anteed 500mA load current with low 150mV dropout.

ꢀ Low Dropout: 150mV @ 500mA

The device is available in two versions (see Table 1).

One version has a high-accuracy output with a preset

voltage (1.2, 1.5, 1.8, 3.0, 3.3, or 4.5V). This voltage is

internally trimmed and also offers a Bypass pin. With a

capacitor connected to this Bypass pin, the PSRR and

the Noise performance is improved.

ꢀ 2.0V to 5.5V Input Voltage

ꢀ Fixed Output Voltage: 1.2V to 5.0V

ꢀ User-Adjustable Output Voltage: 1.2V to 5.3V

ꢀ Power OK Output

At the other version the output voltage is user-adjustable

(1.2V to 5.3V) and offers an SET pin for setting the out-

put voltage.

ꢀ Low Quiescent Current: 40µA

ꢀ Low Shutdown Current: 30nA

ꢀ Thermal Overload Protection

ꢀ Output Current Limit

A low supply current (65µA typ.) at maximum load is

making the device ideal for portable battery-operated

equipment.

3 Applications

The device is ideal for laptops, PDAs, portable audio

devices, mobile phones, cordless phones, and any other

battery-operated portable device.

Other features are included such as an active-low open-

drain reset output that indicates when the output is out

of regulation, a low-current (30nA typ.) shutdown mode,

an integrated short-circuit and a thermal shutdown pro-

tection.

The AS1363 is available in a 6-pin SOT23 package.
