Product details
Overview
TCR2EE275,LM(CT from Toshiba Electronic Devices & Storage Corporation is a 2.75 V fixed-output CMOS low dropout regulator delivering up to 200 mA with 180 mV typical dropout (at 150 mA), 35 μVrms output noise, and ±60 mV load transient response (1 mA ⇔ 150 mA, COUT = 1.0 μF). It features overcurrent protection, auto-discharge, and on/off control input-designed for analog and RF power supply rails where stability and low noise are critical.
For engineers reviewing the TCR2EE275,LM(CT datasheet, TCR2EE275,LM(CT pinout, TCR2EE275,LM(CT application, or TCR2EE275,LM(CT equivalent, key selection criteria include dropout voltage at 150 mA, output accuracy (±1.0 % for 2.75 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 TCR2EE275,LM(CT implements a CMOS-based LDO architecture with integrated P-channel pass transistor, enabling low dropout and fast transient recovery without external compensation. Its control input accepts 0–0.4 V (OFF) and 1.0–5.5 V (ON), supporting direct logic-level enable/disable with internal pull-down.
It operates across −40°C to +85°C with input voltage range 1.5–5.5 V and requires only 0.1 μF input and 1.0 μF output ceramic capacitors. The device achieves 73 dB ripple rejection at 1 kHz and maintains ±1.0 % output accuracy for VOUT ≥ 1.8 V-verified under 50 mA load and 25°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.75 V fixed, ±1.0 % accuracy ensures stable biasing for precision analog/RF ICs |
| Max Output Current | 200 mA DC-supports moderate-power sensor nodes and wireless transceivers |
| Dropout Voltage | 180 mV typ. at 150 mA-enables operation from 2.93 V input while maintaining 2.75 V output |
| Output Noise | 35 μVrms (10 Hz–100 kHz)-minimizes phase noise in VCOs and ADC reference supplies |
| Load Transient Response | ±60 mV deviation (1 mA ⇔ 150 mA step, 1.0 μF COUT)-prevents brownout during burst-mode digital loads |
| Quiescent Current | 35 μA typ. at zero load-extends battery life in always-on IoT endpoints |
| Ripple Rejection | 73 dB at 1 kHz-attenuates switching regulator noise upstream of sensitive analog stages |
Pinout & Package

| 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 2.75 V; connects to ≥1.0 μF ceramic capacitor for stability |
| GND | Ground Reference | Common return path for input/output currents; must be low-impedance |
| CONTROL | Enable/Disable Input | Active-high logic control: <0.4 V = OFF (auto-discharge active), ≥1.0 V = ON |
| NC | No Connect | Internally unused; must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | Actively discharges VOUT when CONTROL = LOW, preventing residual voltage hold-up in power sequencing |
| Ceramic capacitor support | Stable with 1.0 μF COUT and 0.1 μF CIN-eliminates need for bulkier tantalum or aluminum electrolytics |
| Low quiescent current | 35 μA typical at IOUT = 0 mA-critical for battery-powered devices in sleep mode |
| Overcurrent protection | Current-limiting foldback prevents thermal runaway during short-circuit events |
| Pull-down on CONTROL | Internal GND-connected resistor ensures default OFF state if CONTROL is floating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2EF27,LM(CT | Same TCR2EF series, SMV (SOT-25) package-larger footprint (2.8 × 2.9 mm), higher thermal resistance | Preferred where board layout allows larger package and higher power dissipation (580 mW vs. 320 mW) | Select for legacy SOT-25 compatibility or higher ambient temperature operation with board-level heatsinking |
| MCP1700T-275I/TT | Microchip 200 mA LDO; 250 mV dropout (typ. at 250 mA), 65 μVrms noise, no auto-discharge | Lacks active discharge and has higher noise-less suitable for RF or strict sequencing requirements | Choose when cost sensitivity outweighs low-noise or auto-discharge needs; verify COUT stability with 1.0 μF ceramic |
Compared with TCR2EE275,LM(CT, the TCS2EF27,LM(CT offers identical electrical specs but in a larger SOT-25 package with better thermal performance, while the MCP1700T-275I/TT trades lower cost for higher dropout, higher noise, and missing auto-discharge-requiring external discharge circuitry in sequencing-critical systems.

FAQ
What is the maximum input voltage rating for TCR2EE275,LM(CT?
The absolute maximum input voltage for TCR2EE275,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 ratings, and sustained operation above this range risks reliability degradation per Toshiba's derating guidelines.
Does TCR2EE275,LM(CT require an external pull-up on the CONTROL pin?
No, TCR2EE275,LM(CT includes an internal pull-down resistor between CONTROL and GND. The CONTROL pin is active-high: it drives the regulator ON when voltage is ≥1.0 V and OFF when ≤0.4 V. Leaving CONTROL unconnected defaults the device to OFF state due to this internal pull-down-no external pull-up is needed or recommended.
Can TCR2EE275,LM(CT operate with a 0.47 μF output capacitor?
No-TCR2EE275,LM(CT requires a minimum output capacitance of 1.0 μF, as specified in its operating ranges. Using 0.47 μF violates the stability condition and may cause oscillation or degraded load transient response. Only ceramic capacitors with ESR <10 Ω are recommended, and 1.0 μF is the verified minimum for guaranteed stability across temperature and load.
What is the thermal performance difference between ESV and SMV packages for TCR2EE275,LM(CT?
The ESV (SOT-553) package of TCR2EE275,LM(CT has a board-mounted power dissipation rating of 320 mW (on 30 mm × 30 mm × 0.8 mm FR4), while the SMV (SOT-25) variant supports 580 mW (on 25.4 mm × 25.4 mm × 1.6 mm FR4). The ESV's smaller size reduces thermal mass and increases junction-to-ambient resistance, limiting usable power in high-ambient or high-current scenarios unless board layout provides enhanced copper area.
Is TCR2EE275,LM(CT compatible with lead-free reflow soldering processes?
Yes, TCR2EE275,LM(CT is qualified for standard lead-free reflow soldering per JEDEC J-STD-020. Its ESV (SOT-553) package uses matte tin plating and is rated for peak reflow temperatures up to 260°C. The device meets RoHS Directive 2011/65/EU and is marked with appropriate environmental compliance identifiers per Toshiba's public documentation.
