The AS1364 is a low-dropout linear regulator (LDO) designed to operate from 2V to 5.5V input, that delivers a wide range of highly accurate (±0.75%) factory trimmed output voltages as well as adjustable output voltages (using an external resistor-divider network).
The ultra-low dropout device requires only 140mV dropout voltage while delivering a guaranteed 1A load current and is therefore perfectly suited for battery-operated portable applications.
The AS1364 offers extremly low 10μVRMS (100Hz to 100kHz) or 45μVRMS (10Hz to 1MHz) output voltage noise.
| Model | Output Type | BYP | SET |
| AS1364-BTDT-AD | Adjustable | NO | YES |
| AS1364-BTDT-_ _ | Fixed | YES | NO |
The device features an internal PMOS pass transistor (for a low supply current of only 35μA), reset output, a low-power shutdown mode, and protection from shortcircuit and thermal-overload conditions.
The AS1364 is available in an 8-pin TDFN 3x3mm package.
The device is ideal for laptops, PDAs, portable audio devices, mobile phones, cordless phones, and any other battery-operated portable device as well as µC or µP supply.
