TCR2EF115,LM(CT

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

The TCR2EF115,LM(CT is a CMOS single-output low dropout regulator from Toshiba with a fixed 1.15 V output and 200 mA drive capability. It features an on/off control input, overcurrent protection, and an auto-discharge function. The device operates within a 1.5 V to 5.5 V input range and maintains stability with ceramic capacitors (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF). Key electrical characteristics include a typical dropout voltage of 440 mV at 150 mA, quiescent current of 35 μA, ripple rejection ratio of 73 dB at 1 kHz, and load transient response of ±60 mV. Output accuracy is ±18 mV for voltages below 1.8 V.

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

Verify the specific suffix LM(CT) against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with RoHS directives if required by your application standards. Cross-reference the part number with authorized distributors to confirm current availability and lead times. Review the latest datasheet revision for any updates to absolute maximum ratings or thermal derating curves before finalizing procurement orders.

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

Select this component when a fixed 1.15 V rail is required with up to 200 mA load current. Consider the SMV (SOT-25) package for standard surface mount assembly. Evaluate the dropout voltage characteristics relative to your minimum input voltage to ensure regulation under all operating conditions. Verify that the required output capacitance meets the minimum 1.0 μF specification for stability.

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

This device belongs to the TCR2EF series of CMOS linear integrated circuits designed for low noise and fast transient response. It shares architectural similarities with the TCR2EE series but differs in package options and specific output voltage configurations. The series targets sensitive analog and RF applications where power supply integrity is critical.

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

Check for other members of the TCR2EF series with different output voltages if the 1.15 V setting does not match requirements. Verify pinout compatibility with alternative LDO regulators offering similar current capabilities and dropout characteristics.
