TCR3DM11,LF(SE

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

The TCR3DM11,LF(SE is a CMOS low dropout regulator from the TCR3DM series manufactured by Toshiba Semiconductor and Storage. It provides a fixed output voltage of 1.1 V with a maximum output current of 300 mA. The device operates within an input voltage range of 1.75 V to 5.5 V and features a typical dropout voltage of 550 mV at full load. Key electrical characteristics include a quiescent current of up to 78 µA, line regulation of 1 mV, and load regulation of 18 mV. It incorporates over-current protection, over-temperature protection, inrush current protection, and an auto-discharge function.

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

Verify the specific suffix LF(SE) against official Toshiba documentation to confirm package type and tape/reel specifications. Ensure compatibility with RoHS directives and check for any regional export control classifications before procurement. Confirm that the ordering code matches the exact output voltage and thermal requirements of the target application.

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

Select this component for applications requiring a fixed 1.1 V rail with moderate current demands up to 300 mA. Consider the ultra-small DFN4/DFN4E package for space-constrained layouts. Evaluate the thermal dissipation capabilities based on the expected ambient temperature and PCB copper area, as power dissipation ratings are board-dependent.
