Product details
Overview
TCR2LF08,LM(CT) from Toshiba is a 0.8 V fixed-output, 200 mA CMOS low-dropout regulator in SOT-25 (SMV) package, featuring ultra-low 2 μA max quiescent current, 1020 mV typical dropout at 150 mA, ±1.0% output accuracy for ≥1.8 V outputs (0.8 V variant specified as ±18 mV), overcurrent protection, and auto-discharge function-designed for power management in space-constrained portable electronics such as cellular phone baseband ICs.
For engineers reviewing the TCR2LF08,LM(CT) datasheet, TCR2LF08,LM(CT) pinout, TCR2LF08,LM(CT) application, or TCR2LF08,LM(CT) equivalent, key selection criteria include its 0.8 V output stability under light load, compatibility with 0.1 μF ceramic input/output capacitors, on/off control interface with 0–0.4 V OFF threshold, and thermal performance limits in SMV package (200 mW unit rating, 580 mW board-mounted).
Technical Context
The TCR2LF08,LM(CT) implements a CMOS-based LDO architecture with integrated P-channel pass transistor, enabling low dropout and minimal quiescent current across −40°C to +85°C operating range. Its control logic accepts TTL-compatible ON/OFF signals and activates internal discharge path when disabled.
It operates with input voltage from 1.5 V to 5.5 V, supports stable regulation down to 0.8 V output, and maintains <30 mV load regulation (1–150 mA) and <15 mV line regulation (VOUT+0.5 V ≤ VIN ≤ 5.5 V), making it suitable for battery-powered systems where headroom and standby efficiency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8 V ±18 mV (−40°C to +85°C), enabling direct core supply for ultra-low-voltage logic |
| Max Output Current | 200 mA continuous, sufficient for RF transceivers or sensor hubs in compact IoT nodes |
| Quiescent Current | 1.0 μA typ. / 2.0 μA max at IOUT = 0 mA, minimizing battery drain in always-on sleep modes |
| Dropout Voltage | 1020 mV typ. at IOUT = 150 mA (0.8 V output), defining minimum VIN = 1.82 V for full regulation |
| Control Threshold | VCT(OFF) ≤ 0.4 V ensures reliable disable under weak pull-down or open-drain MCU GPIO |
| Capacitor Support | Stable with 0.1 μF ceramic CIN/COUT (ESR < 10 Ω), reducing PCB area vs. tantalum alternatives |
| Thermal Rating | 580 mW max power dissipation on FR4 board (25.4 mm × 25.4 mm × 1.6 mm), limiting max IOUT at high VIN-VOUT |
Pinout & Package
TCR2LF08,LM(CT) uses the SMV (SOT-25/SC-74A) package: 2.8 mm × 2.9 mm × 1.1 mm, 5-pin surface-mount, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 5) | Input power supply connection | Accepts 1.5–5.5 V; requires local 0.1 μF ceramic decoupling within 2 mm |
| VOUT (Pin 1) | Regulated output terminal | Delivers stable 0.8 V; connects directly to load with minimal trace inductance |
| GND (Pin 3) | Power and control reference ground | Shared return for VIN, VOUT, CONTROL; must tie to low-impedance ground plane |
| CONTROL (Pin 2) | Enable/disable logic input | Active-high: ≥1.0 V enables regulation; ≤0.4 V disables output and activates auto-discharge |
| NC (Pin 4) | No-connect terminal | Internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 2.0 μA max at zero load enables >1-year battery life in coin-cell–powered sensors |
| Auto-discharge function | Internal 20 Ω discharge path clears VOUT within microseconds after CONTROL deactivation, preventing backfeed |
| Low-ESR capacitor compatibility | Stable operation with 0.1 μF ceramic caps eliminates need for larger, higher-cost tantalum or aluminum electrolytics |
| Overcurrent protection | Current-limiting circuit prevents damage during short-circuit events without latch-up or thermal shutdown |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-quiescent-current LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2LF08,LM(CT) | Same 0.8 V output, but uses ESV (SOT-553) package (1.6 mm × 1.6 mm); 3.0 mg weight vs. 16.0 mg; 150 mW unit power rating | Higher density placement possible, but lower thermal mass limits sustained 200 mA delivery in confined layouts | Select TCS2LF08,LM(CT) only when board space is constrained and peak load duration is <100 ms |
| XC6206P082MR-G | 0.8 V output, 150 mA max, 1.0 μA quiescent current, SOT-25 package; no auto-discharge or CONTROL pin | Requires external MOSFET for enable/disable; lacks integrated discharge path for rapid VOUT decay | Choose XC6206P082MR-G only if system does not require controlled shutdown sequencing or backfeed prevention |
Compared with TCR2LF08,LM(CT), the TCS2LF08,LM(CT) offers smaller footprint but reduced thermal capacity, while XC6206P082MR-G omits critical control and safety features-making TCR2LF08,LM(CT) the sole choice for designs needing integrated enable, auto-discharge, and full 200 mA capability in SMV.

FAQ
What is the maximum input voltage rating for TCR2LF08,LM(CT)?
The TCR2LF08,LM(CT) has an absolute maximum input voltage (VIN) rating of 6.0 V. Operation above this level risks permanent damage. For reliable continuous use, the recommended input voltage range is 1.5 V to 5.5 V, as specified in electrical characteristics testing conditions. This range ensures optimal dropout performance and thermal stability across the full −40°C to +85°C operating temperature range of the TCR2LF08,LM(CT).
Does TCR2LF08,LM(CT) support ceramic output capacitors?
Yes, TCR2LF08,LM(CT) is fully compatible with 0.1 μF ceramic output capacitors, provided their ESR is below 10 Ω. The device's internal compensation is optimized for low-ESR ceramics, eliminating the need for larger tantalum or aluminum electrolytic capacitors. This capability directly reduces PCB area and cost while improving reliability-key advantages confirmed in Toshiba's Application Note for the TCR2LF08,LM(CT) and verified across all production lots.
What is the dropout voltage of TCR2LF08,LM(CT) at 150 mA load?
The dropout voltage of TCR2LF08,LM(CT) is 1020 mV typical at IOUT = 150 mA and Tj = 25°C, with a maximum of 1580 mV over −40°C to +85°C. This value is specific to the 0.8 V output variant and reflects the minimum VIN – VOUT differential required to maintain regulation. At 150 mA, the TCR2LF08,LM(CT) therefore requires VIN ≥ 1.82 V (0.8 V + 1.02 V) for stable operation under nominal conditions.
How does the CONTROL pin function on TCR2LF08,LM(CT)?
The CONTROL pin on TCR2LF08,LM(CT) is an active-high enable input: applying ≥1.0 V turns the regulator ON, while ≤0.4 V disables it and activates the internal auto-discharge path (20 Ω typical). When disabled, the TCR2LF08,LM(CT) rapidly discharges VOUT to GND, preventing backfeed into upstream supplies-a critical feature for power sequencing in multi-rail systems. The pin includes internal pull-down, allowing direct connection to open-drain MCU GPIO.
Is TCR2LF08,LM(CT) RoHS compliant and lead-free?
Yes, TCR2LF08,LM(CT) is RoHS compliant and lead-free, meeting EU Directive 2011/65/EU requirements. Toshiba confirms this status in its official environmental compliance documentation and product change notices. The SMV (SOT-25) package uses matte tin plating over copper leadframe, with no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE substances above threshold limits. Full material declarations are available upon request for TCR2LF08,LM(CT) through Aetrix Electronics' technical support portal.
