Product details
Overview
TCR2LN36,LF from Toshiba Electronic Devices & Storage Corporation is a fixed-output 3.6 V CMOS low dropout (LDO) voltage regulator with on/off control input, ultra-low 2 μA quiescent current (max), 200 mA output capability, and 200 mV typical dropout voltage at 150 mA load - designed for power management in space-constrained portable electronics.
For engineers reviewing the TCR2LN36,LF datasheet, TCR2LN36,LF pinout, TCR2LN36,LF application, or TCR2LN36,LF equivalent, this device is selected for battery-powered systems requiring high accuracy (±1.0 %), ceramic capacitor compatibility (0.1 μF input/output), auto-discharge functionality, and operation across −40 to 85 °C ambient temperature.
Technical Context
The TCR2LN36,LF integrates a CMOS pass transistor with internal reference, error amplifier, and overcurrent protection circuitry. Its control input enables active-high enable logic (VCT(ON): 1.0–5.5 V) and supports auto-discharge via internal 20 Ω discharge path when disabled.
It operates with minimal external components: only 0.1 μF ceramic capacitors on VIN and VOUT are required for stability. The regulator maintains ±1.0 % output accuracy for VOUT ≥ 1.8 V and achieves 75 ppm/°C temperature coefficient over −40 to 85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.6 V ±1.0 % (guaranteed accuracy enables precise MCU core/sensor rail regulation) |
| Max Output Current | 200 mA (supports moderate-power peripherals like BLE radios or display drivers) |
| Quiescent Current | 2 μA max at zero load (enables multi-year battery life in always-on IoT sensors) |
| Dropout Voltage | 200 mV typ. at 150 mA (allows operation down to VIN = 3.8 V while sustaining 3.6 V output) |
| Input Voltage Range | 1.5 V to 5.5 V (compatible with single-cell Li-ion, Li-poly, or 3.3 V system rails) |
| Package | SDFN4 (0.8 mm × 0.8 mm × 0.38 mm, 0.6 mg weight - fits 0201 footprint constraints) |
| Auto-Discharge | Enabled via internal 20 Ω path (discharges output within milliseconds after shutdown - prevents residual voltage hold-up) |
Pinout & Package
TCR2LN36,LF is housed in the ultra-small SDFN4 package (0.8 mm × 0.8 mm × 0.38 mm), with exposed center pad intended for GND connection or left floating per design requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Power Supply | Accepts 1.5–5.5 V input; requires 0.1 μF ceramic decoupling close to pin |
| CONTROL | Enable/Disable Input | Active-high logic: ≥1.0 V enables regulator; ≤0.4 V disables with auto-discharge activation |
| GND | Ground Reference | System ground return; center pad should be connected to GND for thermal and EMI performance |
| VOUT | Regulated Output | Delivers stable 3.6 V ±1.0 %; requires 0.1 μF ceramic capacitor directly at pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2 μA max at zero load - extends shelf life and runtime in battery-backed real-time clocks and wearables |
| Ceramic capacitor support | Stable with 0.1 μF CIN/COUT - eliminates need for larger tantalum or aluminum electrolytics, saving board area |
| Integrated auto-discharge | 20 Ω internal discharge path - ensures rapid VOUT decay after shutdown, preventing unintended wake-up of downstream ICs |
| High output accuracy | ±1.0 % tolerance for VOUT ≥ 1.8 V - meets tight supply requirements of precision ADCs and RF front-ends |
| Low thermal profile | 0.6 mg mass and 0.38 mm height - minimizes thermal mass and enables dense stacking in multi-layer mobile PCBs |
Applications
| Wearable Health Sensors | Bluetooth Low Energy Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Torex XC6219B362MR-G | Same 3.6 V output, 200 mA rating, but 1.0 μA quiescent current (lower); SOT-25 package (2.9 mm × 2.8 mm) - 4.5× larger footprint | Larger package limits use in ultra-dense layouts; lower IB benefits extreme low-power designs where size is secondary | Select when lowest possible quiescent current is prioritized over board area |
| Rohm BD3572EFJ-ME2 | 3.6 V output, 200 mA, 2.5 μA IB (slightly higher); HTSOP-J8 package (4.0 mm × 4.0 mm) - 25× larger than SDFN4 | Thermal performance superior under sustained 200 mA load; unsuitable for sub-1 mm² layout constraints | Select when continuous full-load operation and thermal margin outweigh miniaturization needs |
Compared with TCR2LN36,LF, the XC6219B362MR-G offers lower quiescent current but sacrifices board area efficiency, while the BD3572EFJ-ME2 provides better thermal handling at the cost of footprint size - making TCR2LN36,LF optimal for applications where ultra-miniature packaging and balanced low-power performance are jointly critical.

FAQ
What is the guaranteed output voltage accuracy of the TCR2LN36,LF?
The TCR2LN36,LF guarantees ±1.0 % output voltage accuracy for its 3.6 V nominal output across operating conditions (Tj = −40 to 85 °C, IOUT = 50 mA). This specification applies specifically to the TCR2LN36,LF variant and is confirmed in Toshiba's official electrical characteristics table - enabling reliable power delivery to precision analog and RF circuits without external trimming.
Does the TCR2LN36,LF require external components for stable operation?
No external compensation is needed. The TCR2LN36,LF is internally compensated and stable with only 0.1 μF ceramic capacitors on both VIN and VOUT pins, as validated in Toshiba's application note and electrical test conditions. This eliminates the need for larger bulk capacitors or ESR-matching networks - a key enabler for the TCR2LN36,LF's use in space-constrained portable designs.
How does the auto-discharge function operate in the TCR2LN36,LF?
When the CONTROL pin voltage drops below 0.4 V (OFF state), the TCR2LN36,LF activates an internal 20 Ω discharge path between VOUT and GND. This rapidly discharges the output capacitor - typically within tens of microseconds - preventing residual voltage from powering downstream circuitry unintentionally. This behavior is intrinsic to the TCR2LN36,LF's silicon design and does not require external FETs or resistors.
What is the maximum allowable input voltage for the TCR2LN36,LF?
The absolute maximum input voltage for the TCR2LN36,LF is 6.0 V, as specified in Toshiba's Absolute Maximum Ratings table. However, for reliable continuous operation, the recommended input voltage range is 1.5 V to 5.5 V - ensuring safe thermal margin and compliance with the device's dropout and power dissipation limits under all load and temperature conditions defined for the TCR2LN36,LF.
Is the center pad on the TCR2LN36,LF's SDFN4 package required to be connected to GND?
The center electrode (exposed pad) of the TCR2LN36,LF's SDFN4 package is recommended to be connected to GND for optimal thermal performance and EMI suppression, though Toshiba's datasheet states it may be left open if thermal or layout constraints prohibit grounding. This pad is not electrically tied to any internal node other than GND, and its connection status does not affect the basic regulation function of the TCR2LN36,LF.
