Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for AS1352

AS1352

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The AS1352 is a high-performance quad CMOS low-dropout voltage regulator housed in a single QFN package. It provides four independent regulators with an output current of 200mA each and supports a supply range of 3V to 5.5V. The device features one-time programmable (OTP) output voltages ranging from 1.8V to 3.3V in 0.1V steps, or factory-trimmed fixed versions. Key electrical parameters include a dropout voltage of 0.2V at 200mA, shutdown current of ≤1µA, and supply current without load of 225µA. Stability is ensured with ceramic capacitors between 1µF and 4.7µF.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Four independent LDOs with digital enable inputs and integrated thermal and over-current protection
One-time programmable architecture allowing onsite voltage configuration or factory-trimmed fixed outputs
Low noise performance suitable for direct connection to sensitive circuits without additional filtering
Optimized stability with low ESR ceramic output capacitors

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Applications

Mobile phones and PDAs
MP3 players and handheld computers

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific ordering suffix to confirm whether the component requires user-side programming via the austriamicrosystems board or arrives as a factory-trimmed version with preset voltages. Ensure the selected package variant matches the required pin count and physical dimensions for the target PCB layout.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select the 12-pin QFN 4x4 or 16-pin QFN 3x3 package based on available board space and routing requirements. Choose the OTP version for design flexibility during prototyping or the factory-trimmed variant for mass production efficiency. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range.
