Toshiba Semiconductor and Storage TCR2EF30,LM(CT

Overview

TCR2EF30,LM(CT) from Toshiba Electronic Devices & Storage Corporation is a 3.0 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 150 mV typical dropout voltage at 150 mA load, 35 μV_rms output noise, and ±60 mV load transient response - designed for powering sensitive analog and RF circuitry in portable and space-constrained systems.

For engineers reviewing the TCR2EF30,LM(CT) datasheet, TCR2EF30,LM(CT) pinout, TCR2EF30,LM(CT) application, or TCR2EF30,LM(CT) equivalent, key selection criteria include its fast transient performance under 1–150 mA step loads, ±1.0% output accuracy (≥1.8 V), 35 μV_rms noise floor, ceramic capacitor compatibility (C_IN = 0.1 μF, C_OUT = 1.0 μF), and on/off control interface with auto-discharge function.

Technical Context

The TCR2EF30,LM(CT) implements a CMOS-based LDO architecture with integrated overcurrent protection and an active pull-down on the CONTROL pin to ensure rapid discharge of output capacitance during shutdown. Its internal reference and error amplifier are optimized for stability with low-ESR ceramic capacitors.

It operates across −40°C to +85°C ambient temperature, supports input voltages from 1.5 V to 5.5 V, and maintains regulation down to VIN = VOUT + 0.5 V (i.e., as low as 3.5 V input for 3.0 V output). The device achieves 73 dB ripple rejection at 1 kHz and exhibits only 100 ppm/°C output voltage drift over temperature.

FAQ

What is the maximum input voltage rating for TCR2EF30,LM(CT)?

The absolute maximum input voltage for TCR2EF30,LM(CT) is 6.0 V. However, the recommended operating input voltage range is 1.5 V to 5.5 V. Exceeding 5.5 V may trigger overvoltage stress even if within absolute maximum ratings, and sustained operation above this range risks reliability degradation per Toshiba's derating guidelines.

Does TCR2EF30,LM(CT) require external components to operate stably?

Yes - TCR2EF30,LM(CT) requires a minimum 0.1 μF ceramic capacitor on VIN and a minimum 1.0 μF ceramic capacitor on VOUT, both placed as close as possible to their respective pins. Toshiba specifies ESR <10 Ω for the output capacitor; no additional compensation network or feedforward capacitor is needed due to internal stability optimization.

How does the CONTROL pin function on TCR2EF30,LM(CT)?

The CONTROL pin on TCR2EF30,LM(CT) is an active-high enable input: applying ≥1.0 V (up to 5.5 V) turns the regulator ON; applying ≤0.4 V forces shutdown and activates the internal auto-discharge path to rapidly deplete VOUT capacitance. An open or floating CONTROL pin defaults to OFF state due to internal pull-down.

What is the thermal performance difference between ESV and SMV packages for TCR2EF30,LM(CT)?

TCR2EF30,LM(CT) in ESV (SOT-553) has a board-mounted power dissipation rating of 320 mW on a 30 mm × 30 mm × 0.8 mm FR4 board, while the SMV (SOT-25) variant supports 580 mW on a 25.4 mm × 25.4 mm × 1.6 mm FR4 board. The ESV's smaller size sacrifices ~45% thermal margin but enables 60% footprint reduction - critical for ultra-dense layouts.

Is TCR2EF30,LM(CT) suitable for automotive applications?

TCR2EF30,LM(CT) is specified for −40°C to +85°C operating temperature and meets industrial-grade reliability standards, but it is not AEC-Q200 qualified. It is suitable for under-dash infotainment peripherals or cabin sensors where full automotive qualification is not mandated; for safety-critical or engine-bay applications, Toshiba's automotive-qualified TAxx series should be used instead.
