Product details

Overview

TCR2EE14,LM(CT from Toshiba Electronic Devices & Storage Corporation is a 1.4 V fixed-output, 200 mA CMOS low dropout (LDO) regulator in SOT-553 (ESV) package, featuring 310 mV typical dropout at 150 mA, 35 μV_rms output noise, ±60 mV load transient response, and Auto-discharge function - designed for analog/RF power rails in portable instrumentation and wireless sensor nodes.

For engineers reviewing the TCR2EE14,LM(CT) datasheet, TCR2EE14,LM(CT) pinout, TCR2EE14,LM(CT) application, or TCR2EE14,LM(CT) equivalent, key selection criteria include dropout voltage at 150 mA, output accuracy (±1.0% for V_OUT ≥ 1.8 V; ±18 mV for 1.4 V), ceramic capacitor compatibility (C_IN = 0.1 μF, C_OUT = 1.0 μF), and thermal performance in ESV package.

Technical Context

The TCR2EE14,LM(CT) implements a CMOS-based LDO architecture with integrated on/off control input and internal pull-down between CONTROL and GND. It operates across 1.5–5.5 V input range and delivers stable 1.4 V output with high ripple rejection (73 dB at 1 kHz) and low quiescent current (35 μA typ. at zero load).

Its fast load transient response (±60 mV step from 1 mA to 150 mA) is enabled by internal compensation optimized for 1.0 μF ceramic output capacitance. Overcurrent protection and Auto-discharge ensure safe shutdown behavior during fault or disable conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 1.4 V (±18 mV accuracy per spec, since V_OUT < 1.8 V)
Max Output Current	200 mA DC - supports moderate-power analog/RF ICs without thermal derating under typical PCB layout
Dropout Voltage	310 mV (typ.) at I_OUT = 150 mA - enables operation from 1.71 V input, critical for single-cell Li-ion or coin-cell systems
Output Noise	35 μV_rms (typ., 10 Hz–100 kHz, 2.5 V ref) - low-noise performance validated for RF biasing and precision ADC references
Load Transient Response	±60 mV (typ., 1 mA ↔ 150 mA step, C_OUT = 1.0 μF) - maintains signal integrity during burst-mode digital activity
Quiescent Current	35 μA (typ., I_OUT = 0 mA) - extends battery life in always-on sensing applications
Ripple Rejection	73 dB (typ., 1 kHz, 2.5 V output) - suppresses switching noise from upstream DC/DC converters

Pinout & Package

TCR2EE14,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.). Pin assignment is identical to SMV (SOT-25) but in smaller footprint.

Pin/Terminal	Circuit Role	Design Meaning
VIN	Input supply connection	Accepts 1.5–5.5 V; requires ≥0.1 μF ceramic decoupling close to pin
VOUT	Regulated output	Delivers fixed 1.4 V; requires ≥1.0 μF ceramic output capacitor for stability
GND	Power ground reference	Low-impedance return path; must be routed with minimal trace inductance
CONTROL	Enable/disable logic input	Active-high: ≥1.0 V turns ON; ≤0.4 V or open disables output and engages Auto-discharge
NC	No-connect terminal	Internally unconnected; must remain floating - no external connection permitted

Key Features

Feature	Design Value
Low dropout voltage	310 mV typ. at 150 mA enables ultra-low-input operation - e.g., 1.71 V minimum for full 1.4 V output
Ceramic capacitor support	Stable with 0.1 μF input + 1.0 μF output ceramics - eliminates need for bulkier tantalum or electrolytic caps
Auto-discharge function	Actively discharges VOUT when CONTROL = LOW or open - prevents residual voltage hold-up in power-gated subsystems
High PSRR	73 dB at 1 kHz suppresses noise from noisy DC/DC sources - critical for mixed-signal SoCs and RF front-ends
Precision output accuracy	±18 mV over temperature ensures consistent biasing for op-amps and ADC references without calibration

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TCS2014B	1.4 V fixed, 200 mA, SOT-23-5; higher dropout (420 mV @ 150 mA), no Auto-discharge	Lacks fast transient response (±120 mV) and active discharge - unsuitable for power-gated systems	Choose only if board space allows larger SOT-23-5 and Auto-discharge is unnecessary
MCP1703T-1402E/MB	1.4 V fixed, 250 mA, SOT-23-5; 600 mV dropout @ 250 mA, 45 μV_rms noise, no CONTROL pin	No enable control or Auto-discharge; higher noise and dropout limit low-input use cases	Select only when simple ON/OFF is sufficient and 1.5 V minimum input is acceptable

Compared with TCR2EE14,LM(CT), both alternatives lack integrated Auto-discharge and exhibit higher dropout or noise - making TCR2EE14,LM(CT) uniquely suited for compact, battery-sensitive designs requiring controlled shutdown and ultra-low-noise 1.4 V regulation.

FAQ

What is the output voltage accuracy of TCR2EE14,LM(CT) across temperature?

The TCR2EE14,LM(CT) has an output voltage accuracy of ±18 mV (not ±1.0%) because its 1.4 V output falls below the 1.8 V threshold specified for the ±1.0% tolerance grade. This ±18 mV tolerance holds over the full operating temperature range of −40°C to +85°C, as confirmed in the Electrical Characteristics table (Note 6).

Can TCR2EE14,LM(CT) operate from a 1.6 V input supply?

No - the TCR2EE14,LM(CT) requires a minimum input voltage of 1.5 V per Operating Ranges, but to deliver rated 1.4 V output at 150 mA, it needs at least VIN = VOUT + VDO = 1.4 V + 0.31 V = 1.71 V. At 1.6 V input, output drops out of regulation; stable operation begins at ≥1.71 V.

Does TCR2EE14,LM(CT) require external resistors for output voltage setting?

No - the TCR2EE14,LM(CT) is a fixed-output LDO with internally trimmed 1.4 V regulation. No external feedback resistors are needed or supported; the device is designed exclusively for single-voltage applications without adjustment.

What is the thermal performance of TCR2EE14,LM(CT) in ESV package?

In the ESV (SOT-553) package, TCR2EE14,LM(CT) has a board-mounted power dissipation rating of 150 mW (unit) and 320 mW (FR4, 30 mm × 30 mm × 0.8 mm). Its 3.0 mg mass and small footprint demand careful PCB copper area design to maintain junction temperature ≤150°C under 200 mA load.

How does the Auto-discharge function work in TCR2EE14,LM(CT)?

When the CONTROL pin is pulled LOW (≤0.4 V) or left open, TCR2EE14,LM(CT) disables the pass transistor and activates an internal discharge path from VOUT to GND. This rapidly depletes stored charge in the output capacitor - verified in Application Note Section 1 - ensuring safe, predictable power-down in sequenced systems.
