AS1356-15-T

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

The AS1356-15-T is a fixed-voltage linear low-dropout regulator (LDO) manufactured by ams OSRAM USA INC. It delivers a nominal output voltage of 1.5V with a maximum output current capability of 150mA. The device operates within an input voltage range of 2.5V to 5.5V and maintains an output voltage accuracy of ±1% at 25°C. Key electrical parameters include a dropout voltage of 40mV at a 100mA load, a shutdown supply current of less than 1µA, and a power-supply rejection ratio of 60dB at 100Hz. It features integrated reverse-battery protection and a Power-OK output indicator.

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

Verify the specific ordering suffix '-T' corresponds to the tape and reel delivery form as documented in the manufacturer's ordering information. Confirm that the '15' designation strictly indicates the 1.5V fixed output voltage variant. Ensure compatibility with the required 5-pin SOT23 package footprint during procurement planning.

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

Select this component when a fixed 1.5V rail is required with minimal external components. The AS1356 variant is preferred over the AS1353 if system monitoring via the Power-OK signal is necessary. Ensure the application utilizes ceramic capacitors with ESR below 0.2Ω for stability. Verify that the input voltage remains within the 2.5V to 5.5V operational window.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the AS1353/AS1356 family of high-performance linear LDOs designed for capacitor ranges of 1 to 10µF. Originally developed by austriamicrosystems AG, technical content remains valid under ams AG. The family shares core architecture including P-channel MOSFET outputs and reverse-battery protection, differentiated primarily by the inclusion of the Power-OK feature in the AS1356 series.
