Product details
Overview
TCR2EN10,LF(SE) from Toshiba Electronic Devices & Storage Corporation is a 1.0 V fixed-output CMOS low-dropout linear regulator in ultra-small SDFN4/SDFN4E package (0.8 mm × 0.8 mm × 0.38 mm), delivering up to 200 mA with 490 mV typical dropout at 150 mA load, ±18 mV output voltage accuracy, and 18 µVrms output noise. It serves as a primary power supply for low-voltage logic rails in space-constrained portable electronics.
For engineers reviewing the TCR2EN10,LF(SE) datasheet, TCR2EN10,LF(SE) pinout, TCR2EN10,LF(SE) application, or TCR2EN10,LF(SE) equivalent, key selection criteria include its 1.0 V fixed output, ultra-low quiescent current (35 µA typ.), Auto-discharge function, on/off control interface, and compatibility with 0.1 µF input / 1.0 µF ceramic output capacitors.
Technical Context
The TCR2EN10,LF(SE) integrates a CMOS pass transistor with internal reference and error amplifier to regulate output voltage under varying load and line conditions. Its control input accepts TTL/CMOS-compatible logic levels (ON threshold ≥1.0 V, OFF threshold ≤0.4 V) and enables fast turn-on/turn-off response with integrated pull-down to GND.
Designed for high-density PCB layouts, it operates across −40°C to +85°C ambient temperature with thermal shutdown protection and overcurrent limiting. The device maintains stability with minimal external components-only two ceramic capacitors-and achieves 73 dB ripple rejection at 1 kHz for noise-sensitive analog and RF subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.0 V ±18 mV (±1.8%); ensures stable core voltage for 1.0 V logic families and low-power microcontrollers. |
| Max Output Current | 200 mA continuous; supports multiple low-power peripherals (e.g., sensors, BLE radios, display drivers) from single rail. |
| Dropout Voltage | 490 mV typ. at 150 mA; enables operation from 1.49 V input, critical for single-cell Li-ion or coin-cell battery systems. |
| Quiescent Current | 35 µA typ. at zero load; extends battery life in always-on monitoring applications like wearables and IoT endpoints. |
| Output Noise | 18 µVrms (10 Hz–100 kHz); minimizes jitter and interference in precision ADCs, audio codecs, and RF front-ends. |
| Ripple Rejection | 73 dB typ. at 1 kHz; suppresses switching noise from upstream DC/DC converters feeding mixed-signal SoCs. |
| Load Transient Response | ±55 mV max deviation (1 mA ↔ 150 mA step, 1.0 µF COUT); maintains regulation during burst-mode processor activity without external compensation. |
Pinout & Package
TCR2EN10,LF(SE) uses the ultra-compact SDFN4/SDFN4E package (0.8 mm × 0.8 mm × 0.38 mm, 0.6 mg weight) with wettable flank terminals for automated optical inspection. Pin 1 (VOUT) and Pin 4 (VIN) are diagonally opposite; Pin 2 (CONTROL) and Pin 3 (GND) occupy the remaining corners. The center thermal pad must be connected to GND for thermal performance and EMI reduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Regulated output terminal | Delivers stable 1.0 V to load; requires 1.0 µF ceramic capacitor placed within 2 mm for transient stability. |
| CONTROL (Pin 2) | Enable/disable logic input | Active-high control: ≥1.0 V = ON, ≤0.4 V = OFF; internal pull-down ensures default OFF state at power-up. |
| GND (Pin 3) | Ground reference and thermal path | Common return for VIN, VOUT, and CONTROL; center pad must be soldered to GND plane for thermal dissipation and noise immunity. |
| VIN (Pin 4) | Input supply terminal | Accepts 1.5–5.5 V input; requires 0.1 µF ceramic capacitor placed adjacent to pin to suppress high-frequency noise. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | Internally discharges VOUT via controlled sink when CONTROL = LOW, preventing residual voltage hold-up in power-gated domains. |
| Ultra-small footprint | SDFN4/SDFN4E package (0.64 mm² area) enables placement beneath BGA packages or in <1.0 mm board gaps for foldable/wearable form factors. |
| Ceramic capacitor compatibility | Stable with 0.1 µF input and 1.0 µF output ceramics (ESR <10 Ω), eliminating need for larger, less reliable tantalum or aluminum electrolytics. |
| Low-noise regulation | 18 µVrms output noise at 1.0 V output enables direct powering of RF synthesizers and high-resolution SAR ADCs without additional LDO filtering. |
| Overcurrent protection | Current-limiting circuit folds back output current above ~250 mA to prevent thermal runaway during short-circuit or overload events. |
Applications
| Smart Wearable Sensors | BLE Wireless Modules |
|---|---|

IC Role / Device Role / Timing Role: Low-noise post-regulator after buck converter; decouples digital switching noise from sensitive analog acquisition paths. Use Value: 18 µVrms output noise meets IEC 60601-2-27 ECG common-mode rejection requirements; Auto-discharge clears residual charge before patient electrode reconnection. | Use Scenario: Powering FPGA configuration memory and I/O banks in DIN-rail mounted edge controllers with limited board area. IC Role / Device Role / Timing Role: Secondary LDO generating 1.0 V for FPGA I/O banks requiring tight voltage tolerance and fast transient recovery.

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-dropout regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B102MR-G | Same 1.0 V output, 200 mA rating, and SOT-25 package; higher 600 mV dropout at 150 mA; no Auto-discharge function. | Lacks active discharge, requiring external circuitry for rapid VOUT decay in power-gated systems. | Select when board space permits SOT-25 and Auto-discharge is unnecessary; verify thermal derating at 85°C ambient. |
| Rohm BD09CUL | 1.0 V output, 150 mA max, DFN1006-4 package (1.0 mm × 0.6 mm); 350 mV dropout at 100 mA; includes thermal shutdown but no CONTROL pin. | Fixed ON operation only-no enable control-limiting use in duty-cycled applications. | Choose for cost-sensitive, always-on 1.0 V rails where enable functionality is redundant and smaller footprint is secondary to price. |
Compared with TCR2EN10,LF(SE), the XC6210B102MR-G trades lower dropout for missing Auto-discharge, while the BD09CUL sacrifices 50 mA drive capability and enable control for marginally smaller size-making TCR2EN10,LF(SE) optimal for space-constrained, battery-powered systems requiring precise sequencing and ultra-low standby current.

FAQ
What is the maximum input voltage rating for TCR2EN10,LF(SE)?
The absolute maximum input voltage for TCR2EN10,LF(SE) is 6.0 V. However, the recommended operating range is 1.5 V to 5.5 V per electrical characteristics testing conditions. Exceeding 5.5 V may degrade long-term reliability even if within absolute maximum ratings, especially at elevated temperatures.
Does TCR2EN10,LF(SE) require an external resistor on the CONTROL pin?
No, TCR2EN10,LF(SE) includes an internal pull-down resistor between CONTROL and GND, ensuring a defined LOW state at power-up. An external resistor is unnecessary unless specific timing or noise immunity requirements dictate a stronger pull-down-consult Toshiba's Application Note for layout guidance.
Can TCR2EN10,LF(SE) be used with a 0.47 µF output capacitor instead of 1.0 µF?
While the datasheet specifies 1.0 µF for guaranteed ±55 mV load transient response, TCR2EN10,LF(SE) remains stable with 0.47 µF ceramic capacitors (ESR <10 Ω). However, transient deviation may increase beyond ±55 mV, and phase margin should be verified in final layout using actual board parasitics.
What is the thermal resistance (θJA) of TCR2EN10,LF(SE) in its SDFN4 package?
Toshiba does not publish θJA for TCR2EN10,LF(SE) as a standalone value. Thermal performance depends entirely on PCB layout: the standard test board (FR4, 40 mm × 40 mm, 50% copper coverage both sides) yields 300 mW power dissipation rating. For accurate junction temperature estimation, use the measured board temperature rise and actual power dissipation (PD = (VIN − 1.0 V) × IOUT).
Is TCR2EN10,LF(SE) RoHS compliant and lead-free?
Yes, TCR2EN10,LF(SE) is RoHS compliant and lead-free. The "LF" in the part number explicitly denotes lead-free plating, and the device meets EU RoHS Directive 2011/65/EU requirements. Full compliance documentation, including substance declarations, is available through Toshiba's official product page or authorized distributors.
