Product details

Overview

TCR2EE295,LM(CT) from Toshiba Electronic Devices & Storage Corporation is a 2.95 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 180 mV typical dropout at 150 mA load, 35 μV_rms output noise, and ±60 mV load transient response (1 mA ↔ 150 mA, C_OUT = 1.0 μF). It features overcurrent protection, auto-discharge, and on/off control input-designed for analog and RF power supply rails in portable instrumentation and wireless sensor nodes.

For engineers reviewing the TCR2EE295,LM(CT) datasheet, TCR2EE295,LM(CT) pinout, TCR2EE295,LM(CT) application, or TCR2EE295,LM(CT) equivalent, key selection criteria include dropout voltage at 150 mA, output accuracy (±1.0% for V_OUT ≥ 1.8 V), quiescent current (35 μA typ.), ripple rejection (73 dB at 1 kHz), and compatibility with 1.0 μF ceramic output capacitors in ESV (SOT-553) packaging.

Technical Context

The TCR2EE295,LM(CT) employs a CMOS pass transistor architecture enabling ultra-low quiescent current (35 μA typ.) and fast load transient recovery without external compensation. Its internal control loop maintains regulation under rapid load steps while suppressing output voltage deviation to ±60 mV using only a 1.0 μF ceramic capacitor.

It integrates an active pull-down circuit between CONTROL and GND, ensuring reliable shutdown with <1.0 μA standby current when V_CT < 0.4 V. The device operates across −40°C to +85°C and supports input voltages from 1.5 V to 5.5 V-making it suitable for single-cell Li-ion, multi-cell alkaline, and intermediate bus applications where low noise and tight output tolerance are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.95 V ±1.0% (guaranteed for stable biasing of RF amplifiers and precision ADCs)
Max Output Current	200 mA DC (supports moderate-power microcontrollers and transceivers without thermal derating)
Dropout Voltage	180 mV typ. at 150 mA (enables operation down to VIN = 3.13 V, ideal for battery-powered systems)
Output Noise	35 μV_rms (10 Hz–100 kHz) (minimizes phase noise in local oscillator supplies)
Ripple Rejection	73 dB typ. at 1 kHz (effectively suppresses switching regulator coupling into sensitive analog stages)
Quiescent Current	35 μA typ. at zero load (extends battery life in always-on sensor nodes)
Control Threshold	V_CT(OFF) ≤ 0.4 V, V_CT(ON) ≥ 1.0 V (compatible with 1.8 V/3.3 V GPIO without level-shifting)

Pinout & Package

TCR2EE295,LM(CT) uses the ESV (SOT-553) package: 1.6 mm × 1.6 mm × 0.55 mm, 5-pin surface-mount, weight 3.0 mg (typ.). This ultra-compact footprint enables high-density PCB layouts in space-constrained IoT modules and wearables.

Pin/Terminal	Circuit Role	Design Meaning
VIN	Input Power Supply	Accepts 1.5–5.5 V; requires ≥0.1 μF ceramic decoupling close to pin
VOUT	Regulated Output	Delivers stable 2.95 V; must be bypassed with ≥1.0 μF ceramic capacitor near IC
GND	Ground Reference	Common return path for input/output currents; low-impedance connection essential for noise control
CONTROL	Enable/Shutdown Input	Active-high logic input; pulls down internally to GND when open or low; enables fast power gating
NC	No Connect	Internally unconnected; must remain floating or grounded per layout guidelines (not used for signal or thermal relief)

Key Features

Feature	Design Value
Auto-discharge function	Actively discharges VOUT via internal FET when disabled-prevents residual voltage hold-up in sequencing-critical systems
Ceramic capacitor support	Stable with 1.0 μF C_OUT and 0.1 μF C_IN; eliminates need for tantalum or electrolytic capacitors, reducing size and improving reliability
High accuracy output	±1.0% tolerance over temperature and line/load conditions-ensures consistent performance in precision analog signal chains
Low-noise regulation	35 μV_rms noise floor enables direct powering of RF front-ends and high-resolution data converters without additional filtering
Fast load transient response	±60 mV deviation during 1 mA ↔ 150 mA step-maintains system stability during burst-mode MCU or radio activity

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TCS20295	Same 2.95 V output, but 300 mA rating and higher dropout (250 mV @ 150 mA); uses SOT-23-5 package	Better suited for higher-current loads; larger footprint and thermal mass limit use in ultra-thin wearables	Select when >200 mA peak current is required and board space allows SOT-23-5
XC6219B295MR-G	2.95 V output, 150 mA max, 120 mV dropout @ 100 mA; 1.0 μF C_OUT compatible; SOT-25 package	Lower current and smaller dropout-but lacks auto-discharge and has higher quiescent current (50 μA)	Choose for cost-sensitive, lower-power designs where fast discharge is not required

Compared with TCR2EE295,LM(CT), TCS20295 offers higher current headroom at the expense of size and dropout, while XC6219B295MR-G trades auto-discharge and ultra-low I_Q for marginally better dropout in a legacy package-making TCR2EE295,LM(CT) optimal for space-constrained, low-noise, battery-gated systems.

FAQ

What is the guaranteed output voltage tolerance for TCR2EE295,LM(CT) across temperature and load?

The TCR2EE295,LM(CT) guarantees ±1.0% output voltage accuracy for V_OUT ≥ 1.8 V, verified across −40°C to +85°C ambient temperature, 1 mA to 150 mA load, and input voltages from V_OUT + 0.5 V to 5.5 V. This specification ensures consistent biasing of precision analog circuits without external trimming.

Can TCR2EE295,LM(CT) operate with a 1.0 μF ceramic output capacitor?

Yes-TCR2EE295,LM(CT) is explicitly characterized and stabilized with a 1.0 μF ceramic capacitor (ESR < 10 Ω) at the VOUT pin. This eliminates reliance on bulkier tantalum or aluminum electrolytic capacitors and supports miniaturized PCB layouts in space-constrained applications like wearables and IoT nodes.

What is the maximum input voltage rating for TCR2EE295,LM(CT)?

The absolute maximum input voltage for TCR2EE295,LM(CT) is 6.0 V, but the recommended operating range is 1.5 V to 5.5 V. Exceeding 5.5 V risks exceeding junction temperature limits or violating safe operating area constraints-even if within absolute maximum ratings-so design margins should enforce VIN ≤ 5.5 V.

Does TCR2EE295,LM(CT) include overcurrent protection?

Yes-TCR2EE295,LM(CT) integrates foldback-type overcurrent protection that limits output current during short-circuit or overload conditions. While this protects the IC from catastrophic failure, Toshiba advises adding external failsafe circuitry in safety-critical systems, as protection does not guarantee suppression of all fault modes.

How does the auto-discharge function work in TCR2EE295,LM(CT)?

When the CONTROL pin is driven low (V_CT ≤ 0.4 V), TCR2EE295,LM(CT) activates an internal discharge FET between VOUT and GND, rapidly draining stored charge from the output capacitor. This prevents unintended wake-up or latch-up in power-gated systems and ensures clean reset sequencing in multi-rail architectures.
