Product details
Overview
TCR2EN30,LF from Toshiba Electronic Devices & Storage Corporation is a 3.0 V fixed-output CMOS low dropout (LDO) voltage regulator in an ultra-small SDFN4/SDFN4E package (0.8 mm × 0.8 mm × 0.38 mm), delivering up to 200 mA with 130 mV typical dropout at 150 mA load, ±1.0% output accuracy, and 35 µVrms output noise - designed for power management in space-constrained portable electronics such as cellular phones and wearables.
For engineers reviewing the TCR2EN30,LF datasheet, TCR2EN30,LF pinout, TCR2EN30,LF application, or TCR2EN30,LF equivalent, this page provides verified technical context, key specifications including dropout voltage, quiescent current, ripple rejection, load transient response, and Auto-discharge functionality - all confirmed for the exact 3.0 V variant.
Technical Context
The TCR2EN30,LF implements a CMOS-based LDO architecture with integrated on/off control input (CONTROL pin), enabling precise system-level power sequencing. It features internal overcurrent protection and an Auto-discharge function that actively discharges the output capacitor when disabled, preventing residual voltage hold-up in battery-powered systems.
Its fast load transient response (±55 mV deviation at 1 mA ↔ 150 mA step with 1.0 µF ceramic output capacitor) and high ripple rejection (73 dB at 1 kHz) are achieved without requiring external compensation, supporting stable operation with minimal 0.1 µF input and 1.0 µF output ceramic capacitors - critical for high-density PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±1.0% (guaranteed for VOUT ≥ 1.8 V) |
| Dropout Voltage | 130 mV (typ.) at IOUT = 150 mA - enables regulation down to VIN = 3.13 V |
| Quiescent Current | 35 µA (typ.) at zero load - extends battery life in standby mode |
| Output Noise | 35 µVrms (10 Hz–100 kHz) - suitable for noise-sensitive analog/RF circuitry |
| Ripple Rejection | 73 dB (typ.) at 1 kHz - suppresses switching noise from upstream DC-DC converters |
| Load Transient Response | ±55 mV (typ.) for 1 mA ↔ 150 mA step - maintains stable supply during processor wake/sleep cycles |
| Standby Current | 0.1 µA (typ.) when CONTROL = 0 V - enables ultra-low-power shutdown |
Pinout & Package
The TCR2EN30,LF is housed in the ultra-small SDFN4/SDFN4E plastic mold package (0.8 mm × 0.8 mm × 0.38 mm, 0.6 mg weight), featuring a bottom-exposed thermal pad (center electrode) recommended to be connected to GND for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input voltage supply | Accepts 1.5–5.5 V input; must be ≥ VOUT + dropout for regulation |
| VOUT | Regulated output | Delivers stable 3.0 V ±1.0% to load; requires 1.0 µF ceramic capacitor |
| GND | Ground reference | Common return path for input, output, and control circuits; connects center thermal pad |
| CONTROL | Enable/disable input | Logic-high (≥1.0 V) enables output; logic-low (≤0.4 V) disables output and activates Auto-discharge |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | Actively discharges VOUT capacitor when CONTROL = LOW, eliminating residual voltage in portable systems |
| Ultra-small SDFN4/SDFN4E package | 0.8 mm × 0.8 mm footprint enables placement in tight spaces like smartphone camera modules |
| Ceramic capacitor compatibility | Supports 0.1 µF input and 1.0 µF output ceramics - eliminates need for bulkier tantalum or electrolytic caps |
| Overcurrent protection | Internal foldback current limiting prevents damage during short-circuit or overload conditions |
| Pull-down on CONTROL pin | Internal pull-down ensures safe default-OFF state if CONTROL is left floating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6210B302MR-G | Same 3.0 V output, 200 mA rating, but uses SOT-25 package (2.9 mm × 2.8 mm); higher 250 mV dropout at 150 mA | Larger footprint limits use in ultra-dense layouts; lacks Auto-discharge function | Choose when board space permits larger package and Auto-discharge is unnecessary |
| Rohm BD33IC0WEFJ-C | 3.3 V output (not 3.0 V); same SDFN package size; 180 mV dropout at 150 mA; no Auto-discharge | Requires system-level voltage tolerance adjustment; not a direct functional replacement for 3.0 V rail | Consider only if 3.3 V is acceptable and Auto-discharge is not required |
Compared with TCR2EN30,LF, the XC6210B302MR-G offers identical output voltage but sacrifices board-area efficiency and transient performance, while the BD33IC0WEFJ-C shifts the output voltage and omits critical power-control features - making TCR2EN30,LF uniquely suited for space- and noise-constrained 3.0 V applications requiring active discharge.

FAQ
What is the maximum input voltage rating for TCR2EN30,LF?
The absolute maximum input voltage for TCR2EN30,LF is 6.0 V. However, for reliable operation under normal conditions, the recommended input voltage range is 1.5 V to 5.5 V - ensuring sufficient headroom above the 3.0 V output while maintaining low dropout and thermal safety. Exceeding 5.5 V may trigger overvoltage stress even if within absolute maximum ratings.
Does TCR2EN30,LF require external compensation components?
No, TCR2EN30,LF is internally compensated and operates stably with only 0.1 µF ceramic input and 1.0 µF ceramic output capacitors. Its design eliminates the need for external resistors or capacitors in the feedback loop, simplifying layout and reducing BOM count - a key advantage for miniaturized applications where board area is constrained.
How does the Auto-discharge function work in TCR2EN30,LF?
When the CONTROL pin is driven LOW (≤0.4 V), TCR2EN30,LF disables the output and activates an internal discharge transistor between VOUT and GND. This rapidly bleeds charge from the output capacitor, preventing residual voltage that could interfere with system reset or cause unintended peripheral wake-up - a critical feature for battery-powered devices requiring clean power sequencing.
What is the thermal performance of TCR2EN30,LF in its SDFN4/SDFN4E package?
TCR2EN30,LF in the SDFN4/SDFN4E package has a typical thermal resistance θJA of approximately 250°C/W on a standard FR4 board (40 mm × 40 mm, 50% copper coverage). With a maximum junction temperature of 150°C and ambient up to 85°C, it supports continuous 200 mA output only with adequate PCB copper pour and thermal vias beneath the center GND pad - essential for sustained high-load operation.
Is TCR2EN30,LF RoHS compliant and lead-free?
Yes, TCR2EN30,LF is RoHS compliant and lead-free, as confirmed by Toshiba's official product documentation and environmental compliance statements. The ",LF" suffix explicitly denotes lead-free termination, and the device meets EU RoHS Directive 2011/65/EU requirements - making it suitable for commercial and industrial applications requiring environmentally regulated components.
