Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for L4936EH

L4936EH

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

The L4936EH is a monolithic dual voltage regulator in a Multiwatt-15 package, designed for microcomputer systems. It features a 100mA standby output (OUT1) regulated at 5V ±1% and a 400mA output (OUT2) fixed at 5V ±2% or adjustable via an external divider. Operating supply ranges from 5V to 28V DC with 40V transient tolerance. Quiescent current drops below 90μA in standby. Integrated functions include a programmable power-on reset (3.8V–4.7V threshold), input voltage sense comparator, and thermal shutdown.

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

Dual low-dropout regulators providing independent 100mA and 400mA outputs
Integrated power-on reset generator with adjustable threshold and delay
Input voltage sense comparator for system supervision
Negative transient protection on Enable and Sense inputs

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

Automotive microprocessor power supplies
Microcomputer controlled systems
Standby power regulation for embedded controllers

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

Verify the Multiwatt-15 pinout configuration against the datasheet diagram before integration. Confirm that the obsolete status does not conflict with long-term availability requirements. Ensure thermal management meets the junction-to-case resistance specifications for the specific PCB copper area.

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

Select this component when two distinct regulated rails are required from a single automotive-grade source. The adjustable reset threshold allows customization for specific microcontroller brown-out requirements. Verify that the 400mA load capability of Output 2 aligns with peak system demands.

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

This part belongs to the L4936 family of advanced voltage regulators. The 'H' suffix specifically denotes the Multiwatt-15 package variant, which provides additional pins compared to the standard Multiwatt-11 version while maintaining identical electrical characteristics and functionality.
