Product details
Overview
TCR2DG30,LF from Toshiba Electronic Devices & Storage Corporation is a fixed-output, 3.0 V, 200 mA ultra-low-dropout linear voltage regulator in WCSP4 package with 150 mV typical dropout at full load, 75 dB PSRR at 1 kHz, and 30 µA quiescent current-designed for noise-sensitive camera modules and Bluetooth subsystems requiring stable low-noise supply under dynamic load.
For engineers reviewing the TCR2DG30,LF datasheet, TCR2DG30,LF pinout, TCR2DG30,LF application, or TCR2DG30,LF equivalent, key selection criteria include its 3.0 V fixed output, WCSP4 footprint (0.42 mm²), 75 dB PSRR at 1 kHz, 30 µA IQ, and fast load transient response for sensor and RF power rail stabilization.
Technical Context
The TCR2DG30,LF employs CMOS-based control architecture with internal P-channel MOSFET pass device, enabling ultra-low dropout and high PSRR across 10 Hz–100 kHz. It integrates thermal shutdown, over-current protection, auto-discharge, and soft-start to ensure safe startup and fault recovery in compact embedded systems.
Its WCSP4 package supports board-level reliability with solder-joint stress relief and minimal thermal resistance (θJA ≈ 280°C/W), while the 3.0 V output is factory-trimmed to ±1.0% initial accuracy and maintains ±2.0% line/load regulation over temperature and input variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±1.0% (ensures precise biasing for 3.3 V–tolerant I/O without external feedback) |
| Max Output Current | 200 mA (supports single-sensor node or low-power RF transceiver without derating) |
| Dropout Voltage | 150 mV typ. at 200 mA (enables operation down to 3.15 V input, critical for Li-ion battery discharge tail) |
| PSRR | 75 dB at 1 kHz (suppresses switching noise from DC-DC converters feeding adjacent rails) |
| Quiescent Current | 30 µA (extends battery life >1 year in always-on IoT sensor sleep mode) |
| Operating Input Range | 2.0 V to 5.5 V (covers wide battery and system rail compatibility) |
| Load Transient Response | ≤50 µs recovery time (stabilizes output within 2% after 10–90% 100 mA step load change) |
Pinout & Package
TCR2DG30,LF uses Toshiba's WCSP4 (Wafer Chip Scale Package, 4-terminal) with 0.42 mm² footprint and 0.37 mm height-optimized for space-constrained camera modules and wearable sensors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Power Supply | Accepts 2.0–5.5 V; requires local 1 µF ceramic decoupling for PSRR integrity |
| VOUT | Regulated Output | Delivers stable 3.0 V ±1.0%; connects directly to load with ≤10 cm trace length for transient stability |
| GND | Ground Reference | Low-impedance return path; must be tied to PCB ground plane under package for thermal and noise performance |
| CE | Chip Enable | Active-high logic control; pulls low to disable regulator and reduce IQ to <1 µA for system power gating |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Dropout | 150 mV at 200 mA enables use with depleted Li-ion (3.2 V min) and extends usable battery capacity |
| High PSRR (75 dB @ 1 kHz) | Rejects ripple from shared buck converter outputs, preventing noise coupling into analog sensor front-ends |
| Auto-Discharge Function | Internally discharges VOUT to GND when CE = low, eliminating hold-up voltage that could delay system reset |
| Soft-Start | Controls output ramp rate to limit inrush current (<10 mA peak), protecting upstream power sources and reducing EMI |
| Thermal Shutdown | Activates at 150°C junction temperature and latches off until thermal recovery, preventing damage during sustained overload |
Applications
| Camera Module Power | Bluetooth LE Subsystem |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2DG30,LF | Same WCSP4 package and 3.0 V output, but 50 µA IQ and 65 dB PSRR at 1 kHz | Suitable for cost-sensitive designs where 10 dB PSRR margin and 20 µA higher IQ are acceptable | Select if lower BOM cost outweighs PSRR and quiescent current requirements |
| XC6210B302MR-G | 3.0 V SOT-25 LDO with 250 mA rating, 200 mV dropout, 60 dB PSRR, 25 µA IQ | Requires larger PCB area (SOT-25 vs WCSP4) but offers better thermal dissipation for continuous 200 mA loads | Select when thermal headroom > footprint minimization, or when SMT rework compatibility is prioritized |
Compared with TCR2DG30,LF, TCS2DG30,LF trades PSRR and IQ for cost, while XC6210B302MR-G sacrifices miniaturization for thermal robustness-making TCR2DG30,LF optimal for height-constrained, noise-critical, battery-sensitive applications.

FAQ
What is the maximum input voltage rating for TCR2DG30,LF?
The TCR2DG30,LF supports an absolute maximum input voltage of 6.0 V per Toshiba's official datasheet. Its recommended operating range is 2.0 V to 5.5 V. Exceeding 6.0 V risks permanent damage to the internal CMOS pass device and protection circuitry. For reliable long-term operation in battery-powered systems, input should remain within 2.0–5.5 V, especially considering the 3.0 V output and 150 mV dropout margin.
Does TCR2DG30,LF require an external output capacitor for stability?
Yes, TCR2DG30,LF requires a minimum 1.0 µF ceramic output capacitor with X5R or X7R dielectric placed within 2 mm of the VOUT pin. Toshiba specifies this for phase margin assurance and transient response integrity. Using less capacitance or high-ESR capacitors may cause oscillation or excessive overshoot during load steps. The capacitor must also be rated for ≥6.3 V to accommodate input transients.
How does the auto-discharge function operate in TCR2DG30,LF?
When the CE pin is driven low, TCR2DG30,LF disables regulation and activates an internal 200 Ω discharge path between VOUT and GND. This discharges the output capacitor to <0.1 V within ~1 ms (typ.) for a 1 µF load, ensuring rapid power-down and eliminating residual voltage that could interfere with system reset sequencing or cause unintended wake-up in downstream logic.
Is TCR2DG30,LF compatible with lead-free reflow soldering processes?
Yes, TCR2DG30,LF is qualified for lead-free reflow per JEDEC J-STD-020D. Its WCSP4 package supports peak reflow temperatures up to 260°C for 30 seconds. The device meets RoHS Directive 2011/65/EU and is halogen-free. PCB layout must observe Toshiba's recommended pad geometry and stencil aperture to ensure void-free solder joints and mechanical reliability under thermal cycling.
What is the thermal shutdown threshold and recovery behavior of TCR2DG30,LF?
TCR2DG30,LF triggers thermal shutdown at approximately 150°C junction temperature and remains latched off until the die cools to ~135°C. During shutdown, output drops to 0 V and quiescent current falls below 1 µA. Recovery is automatic and non-latching-no external reset is required. This protects against sustained overload or poor heatsinking in confined enclosures without compromising system-level fault handling.
