AS1356-36-T

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

The AS1356-36-T is a fixed-voltage linear low-dropout regulator (LDO) manufactured by ams AG, delivering a nominal output of 3.6V with a maximum load current of 150mA. It operates within an input voltage range of 2.5V to 5.5V and features ultra-low dropout characteristics, achieving as low as 40mV at a 100mA load. The device incorporates integrated P-channel MOSFET technology for efficient power management, alongside comprehensive protection mechanisms including over-current limiting, thermal shutdown, and reverse-battery protection. Additionally, it provides a Power-OK (POK) open-drain output to monitor regulation status.

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

• Integrated Power-OK (POK) circuitry providing active-low indication of out-of-regulation conditions
• Ultra-low dropout performance enabled by internal P-channel MOSFET pass transistor
• Built-in reverse-battery protection disconnects internal circuitry upon incorrect polarity connection
• Active-low shutdown logic reduces supply current to less than 1µA when activated

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

• Powering microprocessors in handheld devices
• Supplying cordless and mobile phones
• Powering MP3 players and digital cameras
• Providing regulated voltage for battery-powered PDAs

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

Verify the specific ordering suffix matches the required output voltage and package configuration before procurement. Confirm that the component meets RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for any specific handling requirements related to moisture sensitivity levels during storage and assembly processes.

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

Select this component when a stable 3.6V rail is required for portable electronics. The integrated Power-OK feature makes it suitable for systems requiring precise power monitoring. Ensure the application utilizes ceramic capacitors with low ESR to maintain stability. Verify that the input voltage remains within the specified 2.5V to 5.5V range under all operating conditions.

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

This part belongs to the AS1353/AS1356 family of linear LDO regulators designed for low-power applications. While the AS1353 lacks the Power-OK pin, the AS1356 variant includes this diagnostic feature. Both share identical electrical characteristics regarding current limits, dropout voltage, and protection circuits, differing primarily in the presence of the monitoring output.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct functional substitutes within the same family include the AS1353 series for applications not requiring the Power-OK signal. Other fixed-voltage variants such as AS1356-33-T or AS1356-27-T offer different output voltages but maintain the same package and pinout compatibility.
