Product details
Overview
TCR2EE36,LM(CT from Toshiba Electronic Devices & Storage Corporation is a 3.6 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 150 mV typical dropout voltage at full load, 35 μVrms output noise, and ±60 mV load transient response - designed for analog/RF power rails in portable instrumentation and wireless sensor nodes.
For engineers reviewing the TCR2EE36,LM(CT datasheet, TCR2EE36,LM(CT pinout, TCR2EE36,LM(CT application, or TCR2EE36,LM(CT equivalent, this page delivers verified package mapping (ESV/SOT-553), on/off control interface behavior, Auto-discharge functionality, and real-world stability conditions using 1.0 μF ceramic output capacitance.
Technical Context
The TCR2EE36,LM(CT implements a CMOS-based LDO architecture with integrated P-channel pass transistor, enabling ultra-low quiescent current (35 μA typ.) and fast load transient recovery without external compensation. Its CONTROL pin supports active-high enable logic with defined ON/OFF thresholds (1.0–5.5 V / 0–0.4 V).
It operates across −40°C to +85°C with input voltage range 1.5–5.5 V, output accuracy ±1.0% (for VOUT ≥ 1.8 V), and ripple rejection of 73 dB at 1 kHz - optimized for noise-sensitive signal chains where supply rail integrity directly impacts ADC SNR or RF front-end phase noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6 V ±1.0% (ensures stable biasing for 3.3 V–3.6 V logic and RF ICs without trimming) |
| Max Output Current | 200 mA DC (supports moderate-power microcontrollers, transceivers, and analog front-ends) |
| Dropout Voltage | 150 mV typ. at IOUT = 150 mA (enables operation from 3.75 V Li-ion single-cell with margin) |
| Output Noise | 35 μVrms (10 Hz–100 kHz) (minimizes contribution to baseband noise in precision ADCs or VCOs) |
| Load Transient Response | ±60 mV (1 mA ⇔ 150 mA step, COUT = 1.0 μF) (maintains regulation during digital core wake-up bursts) |
| Quiescent Current | 35 μA typ. at zero load (extends battery life in always-on sensor nodes) |
| Ripple Rejection | 73 dB typ. at 1 kHz (attenuates switching regulator coupling from upstream DC/DC stages) |
| Enable Threshold | VCT(ON) ≥ 1.0 V; VCT(OFF) ≤ 0.4 V (compatible with 1.8 V/3.3 V GPIO without level-shifting) |
Pinout & Package
TCR2EE36,LM(CT is packaged in ESV (SOT-553), a 1.6 mm × 1.6 mm × 0.55 mm ultra-small surface-mount package weighing 3.0 mg (typ.), optimized for space-constrained wearables and IoT edge nodes.
| 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 3.6 V; requires ≥1.0 μF ceramic capacitor with ESR <10 Ω |
| GND | Ground Reference | Common return path for VIN, VOUT, and CONTROL; must be low-impedance plane |
| CONTROL | Enable/Disable Input | Active-high logic: ≥1.0 V enables regulator; ≤0.4 V disables with 0.1 μA standby current |
| NC | No Connect | Internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge Function | Actively discharges VOUT when disabled, preventing residual voltage hold-up in power-gated subsystems |
| Ceramic Capacitor Compatibility | Stable with 0.1 μF input and 1.0 μF output ceramic caps - eliminates need for tantalum or electrolytic |
| Overcurrent Protection | Current-limiting folds back under short-circuit to protect device and source supply |
| Low Temperature Drift | 100 ppm/°C output voltage drift ensures accuracy across −40°C to +85°C industrial range |
| Pull-down on CONTROL | Internal pull-down ensures default OFF state if CONTROL is left unconnected or high-impedance |
Applications
| Portable Medical Sensors | Wireless IoT Endpoints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2EF36,LM(CT | Same TCR2xx family, SMV (SOT-25) package - larger footprint (2.8 × 2.9 mm), higher thermal dissipation (200 mW unit rating vs. 150 mW for ESV) | Better suited for higher ambient temperature or continuous 200 mA loads where PCB area permits | Select when thermal margin > electrical performance is priority; not pin-compatible due to different pinout (SMV has 5-pin SOT-25 vs. ESV's 5-pin SOT-553 with same pin numbering but smaller pitch) |
| MCP1703T-3602E/MB | Microchip 3.6 V LDO; 250 mA, 600 mV dropout, 65 μVrms noise, SOT-23-5 package | Higher dropout and noise limit use in ultra-sensitive RF/analog apps; lacks Auto-discharge | Use only where cost sensitivity outweighs noise/transient performance; requires redesign for CONTROL pin logic and discharge path |
Compared with TCR2EE36,LM(CT, the TCS2EF36,LM(CT offers superior thermal headroom in larger packages, while the MCP1703T-3602E/MB trades noise/transient performance for broader vendor availability - neither is pin-compatible, and both require layout revision and validation of enable timing and discharge behavior.

FAQ
What is the recommended input and output capacitor configuration for TCR2EE36,LM(CT?
TCR2EE36,LM(CT requires a minimum 0.1 μF ceramic capacitor at VIN and 1.0 μF ceramic capacitor at VOUT, both placed as close as possible to their respective pins. Toshiba specifies ESR <10 Ω for the output capacitor to ensure stability. These values are validated for all operating conditions including load transients and temperature extremes - no additional bulk capacitance is needed for standard use cases.
Does TCR2EE36,LM(CT support automatic discharge of the output when disabled?
Yes, TCR2EE36,LM(CT includes an integrated Auto-discharge function. When the CONTROL pin is pulled low (≤0.4 V), the device actively discharges the VOUT node through an internal path, eliminating residual voltage that could cause unintended operation in downstream circuitry. This behavior is confirmed in Toshiba's Electrical Characteristics table and Application Note section.
What is the maximum junction temperature and thermal derating guidance for TCR2EE36,LM(CT in ESV package?
The absolute maximum junction temperature for TCR2EE36,LM(CT is 150°C. In the ESV (SOT-553) package, the unit power dissipation rating is 150 mW, rising to 320 mW when mounted on a 30 mm × 30 mm × 0.8 mm FR4 board with 20 mm² copper area. Designers must calculate actual power dissipation (PD = (VIN − 3.6 V) × IOUT) and apply derating curves from Toshiba's PD–Ta graph to ensure Tj remains within limits.
How does the CONTROL pin interface work on TCR2EE36,LM(CT, and what happens if it's left unconnected?
The CONTROL pin on TCR2EE36,LM(CT is active-high with VCT(ON) ≥ 1.0 V and VCT(OFF) ≤ 0.4 V. An internal pull-down resistor ensures the device defaults to OFF state if CONTROL is left floating or high-impedance - preventing unintended power-up. This behavior is explicitly documented in Toshiba's Absolute Maximum Ratings and Operating Ranges tables.
Is TCR2EE36,LM(CT compatible with 1.8 V GPIO for enable/disable control?
Yes, TCR2EE36,LM(CT is fully compatible with 1.8 V logic-level GPIO. Its CONTROL pin accepts VCT = 0–5.5 V, with guaranteed turn-on at ≥1.0 V and turn-off at ≤0.4 V. A 1.8 V GPIO output satisfies the VCT(ON) threshold with 0.8 V margin, ensuring robust noise immunity and eliminating need for external level-shifting circuitry.
