Product details
Overview
TCR2LN30,LF from Toshiba Electronic Devices & Storage Corporation is a fixed-output 3.0 V CMOS low dropout (LDO) voltage regulator with on/off control input, ultra-low 2 μA quiescent current (max), 200 mV dropout at 150 mA load, and ±1.0% output accuracy - designed for power management in space-constrained portable electronics such as cellular phones and wearables.
For engineers reviewing the TCR2LN30,LF datasheet, TCR2LN30,LF pinout, TCR2LN30,LF application, or TCR2LN30,LF equivalent, this device offers verified performance in high-density board designs requiring ceramic capacitor compatibility (0.1 μF input/output), auto-discharge functionality, overcurrent protection, and operation across −40°C to +85°C ambient temperatures.
Technical Context
The TCR2LN30,LF implements a CMOS-based LDO architecture with integrated control logic enabling ON/OFF operation via a dedicated CONTROL pin. Its ultra-low quiescent current is achieved through optimized bias circuitry that maintains regulation while drawing only 2 μA (max) at zero load and 0.1 μA (typ.) in standby mode.
It features an internal auto-discharge path (20 Ω typical on-resistance) activated when CONTROL is pulled low, ensuring rapid VOUT discharge during shutdown. The regulator supports stable operation with minimal external components - only two 0.1 μF ceramic capacitors - due to its inherent phase margin design and low ESR tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±1.0% (ensures precise rail generation for 3.0 V logic and RF subsystems) |
| Max Output Current | 200 mA (supports moderate-power microcontrollers, sensors, and RF front-ends) |
| Dropout Voltage | 200 mV (typ.) at 150 mA (enables regulation down to VIN = 3.2 V, extending battery runtime) |
| Quiescent Current | 2 μA (max) at IOUT = 0 mA (minimizes standby power loss in always-on IoT nodes) |
| Input Voltage Range | 1.5 V to 5.5 V (compatible with single-cell Li-ion, Li-poly, and multi-cell alkaline sources) |
| Control Logic | Active-high CONTROL pin (VCT(ON) ≥ 1.0 V; VCT(OFF) ≤ 0.4 V) with internal pull-down (eliminates need for external resistor) |
| Package | SDFN4 (0.8 mm × 0.8 mm × 0.38 mm, 0.6 mg weight) - one of the smallest surface-mount LDO packages available |
Pinout & Package
TCR2LN30,LF is housed in the ultra-compact SDFN4 package (0.8 mm × 0.8 mm × 0.38 mm), featuring a bottom-exposed thermal pad (center electrode) that must be connected to GND or left floating per Toshiba's mounting recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Power Supply | Accepts 1.5–5.5 V input; requires 0.1 μF ceramic decoupling capacitor placed adjacent to pin |
| CONTROL | Enable/Disable Control Input | Active-high logic input; internal 0.1 μA pull-down ensures default OFF state; no external pull-down needed |
| GND | Ground Reference | Common return path for input, output, and control circuits; connects to thermal pad for improved heat dissipation |
| VOUT | Regulated Output | Delivers stable 3.0 V ±1.0%; supports 0.1 μF ceramic output capacitor; enables auto-discharge when CONTROL = LOW |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2 μA (max) at zero load - extends battery life in always-on sensor nodes and wearable devices |
| Low dropout voltage | 200 mV (typ.) at 3.0 V/150 mA - sustains regulation under deep battery discharge conditions |
| Auto-discharge function | 20 Ω typical discharge path - rapidly clears output capacitance during shutdown to prevent back-powering |
| Ceramic capacitor compatibility | Stable with 0.1 μF CIN and COUT - eliminates need for larger, less reliable tantalum or aluminum electrolytics |
| High output accuracy | ±1.0% over 1.8–3.6 V range - ensures reliable operation of precision analog and digital loads without post-regulation trimming |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2120-3.0 | Higher quiescent current (15 μA typ.), same SDFN4 package, no auto-discharge | Lacks active discharge path - unsuitable where fast VOUT decay is required for reset integrity | Select if lower cost is prioritized and auto-discharge is not needed |
| XC6219B302MR-G | Same 3.0 V output, 1.0 μA IQ (typ.), but uses SOT-25 package (2.9 mm × 2.8 mm) - 9× larger footprint | Requires more PCB area; lacks integrated pull-down on CE pin (needs external resistor) | Select if higher thermal mass or legacy layout compatibility is required |
Compared with TCR2LN30,LF, TCS2120-3.0 trades ultra-low IQ for reduced feature set, while XC6219B302MR-G delivers lower quiescent current in a much larger package - making TCR2LN30,LF the optimal choice for space- and power-critical portable designs demanding both miniaturization and functional completeness.

FAQ
What is the maximum input voltage rating for TCR2LN30,LF?
The TCR2LN30,LF has an absolute maximum input voltage (VIN) rating of 6.0 V. However, its 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 maximum limits, and sustained operation above this range risks reliability degradation per Toshiba's derating guidelines. Always maintain VIN ≤ 5.5 V in normal use of TCR2LN30,LF.
Does TCR2LN30,LF require external resistors for the CONTROL pin?
No, TCR2LN30,LF includes an internal pull-down connection between CONTROL and GND, drawing only 0.1 μA typical. This eliminates the need for an external pull-down resistor. The CONTROL pin is active-high with VCT(ON) ≥ 1.0 V and VCT(OFF) ≤ 0.4 V, and its internal design ensures reliable default-OFF behavior - a key simplification confirmed in the TCR2LN30,LF datasheet Pin Assignment section.
Can TCR2LN30,LF operate with 0.1 μF ceramic capacitors on both input and output?
Yes, TCR2LN30,LF is fully characterized and guaranteed to operate stably with 0.1 μF ceramic capacitors on both VIN and VOUT pins, as specified in Toshiba's Electrical Characteristics table and Application Note. The device's internal compensation is optimized for low-ESR ceramics, and Toshiba recommends keeping ESR below 10 Ω - a requirement easily met by standard X5R/X7R 0.1 μF MLCCs used with TCR2LN30,LF.
What is the dropout voltage of TCR2LN30,LF at full 200 mA load?
The dropout voltage of TCR2LN30,LF is not characterized at 200 mA in the official datasheet; specifications are provided up to 150 mA, where VDO = 200 mV (typ.) at 3.0 V output. At 200 mA, the device remains functional but VDO increases beyond 200 mV - exact values depend on junction temperature and layout. For designs requiring guaranteed performance at 200 mA, refer to the "Dropout voltage" table in the TCR2LN30,LF datasheet (Note 4, Tj = −40 to +85°C).
Is the thermal pad on the SDFN4 package of TCR2LN30,LF required to be soldered to GND?
No - the center electrode (thermal pad) of the TCR2LN30,LF SDFN4 package may be connected to GND or left open (unconnected), as explicitly stated in Toshiba's Pin Assignment diagram. While connecting it to GND improves thermal performance and is recommended for high-current or high-ambient-temperature operation, it is not mandatory for basic functionality. The TCR2LN30,LF datasheet confirms either configuration is acceptable per design requirements.
