Product details
Overview
TCR2EF11,LM(CT from Toshiba Electronic Devices & Storage Corporation is a 1.1 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 440 mV typical dropout voltage at 150 mA load, 35 μVrms output noise, and ±60 mV load transient response (1 mA ⇔ 150 mA, COUT = 1.0 μF). It features on/off control input, overcurrent protection, auto-discharge function, and supports ceramic input/output capacitors (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF), making it suitable for analog sensor power rails and RF front-end biasing in portable IoT devices.
For engineers reviewing the TCR2EF11,LM(CT datasheet, TCR2EF11,LM(CT pinout, TCR2EF11,LM(CT application, or TCR2EF11,LM(CT equivalent, key selection criteria include its 1.1 V output accuracy (±1.0 % for VOUT ≥ 1.8 V; ±18 mV for VOUT < 1.8 V), low 35 μA quiescent current, 73 dB ripple rejection at 1 kHz, and compatibility with SOT-25 (SMV) and SOT-553 (ESV) packages for space-constrained designs.
Technical Context
The TCR2EF11,LM(CT implements a CMOS-based LDO architecture with integrated P-channel pass transistor, enabling low dropout operation and fast transient recovery via internal compensation optimized for 1.0 μF ceramic output capacitance. Its control input accepts 0–0.4 V for shutdown (standby current ≤ 1.0 μA) and 1.0–5.5 V for active operation, with pull-down logic ensuring default-off behavior when unconnected.
Designed for stable operation across −40°C to +85°C ambient, the device maintains output regulation under line variations (1.5–5.5 V input), load steps (1–150 mA), and temperature drift (100 ppm/°C TCVO), while meeting strict noise and PSRR requirements for sensitive analog/RF circuitry-e.g., ADC reference supplies and low-noise amplifier biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.1 V ±18 mV (−40°C to +85°C), enabling precise low-voltage core/bias rail for 1.2 V–1.8 V logic domains. |
| Dropout voltage | 440 mV typ. at IOUT = 150 mA, allowing operation with VIN as low as 1.54 V while sustaining full 200 mA output. |
| Output noise | 35 μVrms (10 Hz–100 kHz), minimizing jitter and SNR degradation in precision analog signal chains. |
| Ripple rejection | 73 dB typ. at 1 kHz, suppressing switching noise from upstream DC/DC converters feeding mixed-signal systems. |
| Quiescent current | 35 μA typ. at zero load, supporting >10-year battery life in always-on sensor nodes. |
| Load transient response | ±60 mV deviation during 1 mA ↔ 150 mA step (COUT = 1.0 μF), maintaining stability without external compensation. |
| Operating temperature | −40°C to +85°C junction range, validated for industrial-grade embedded applications without derating. |
Pinout & Package
TCR2EF11,LM(CT is packaged in SMV (SOT-25/SC-74A), a 5-pin surface-mount package measuring 2.8 mm × 2.9 mm × 1.1 mm with 16 mg typical weight. Pin assignment is standardized across the TCR2EF/EE series.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.5–5.5 V; requires ≥0.1 μF ceramic decoupling close to pin to ensure stability and EMI suppression. |
| VOUT | Regulated output terminal | Delivers fixed 1.1 V; must be bypassed with ≥1.0 μF ceramic capacitor directly at pin for transient response compliance. |
| GND | Power ground reference | Low-impedance return path for both input and output currents; requires solid copper pour to minimize noise coupling. |
| CONTROL | Enable/disable logic input | Active-high control: 0–0.4 V = OFF (≤1.0 μA standby), 1.0–5.5 V = ON; internal pull-down ensures safe default-off state. |
| NC | No-connect terminal | Unbonded pin; must remain floating-no routing or soldering permitted to avoid parasitic coupling or mechanical stress. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | Internally discharges VOUT through a 200 Ω switch when CONTROL = LOW, preventing residual voltage hold-up in power sequencing. |
| Ceramic capacitor support | Stable with CIN = 0.1 μF and COUT = 1.0 μF ceramic types (ESR < 10 Ω), eliminating need for bulk tantalum or electrolytic capacitors. |
| Overcurrent protection | Current-limiting folds back at ~250 mA to prevent thermal runaway during short-circuit events, with automatic recovery on fault removal. |
| High accuracy output | ±1.0 % tolerance for outputs ≥1.8 V; ±18 mV absolute error for 1.1 V output ensures reliable margin for sub-1.2 V logic interfaces. |
| Low thermal resistance | SMV package achieves 580 mW board-mounted power dissipation on 25.4 mm × 25.4 mm FR4, enabling 200 mA operation at +70°C ambient. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2EF11,LM(CT | Same 1.1 V output, identical SMV/ESV packaging, but rated for 300 mA output and higher 750 mW board power dissipation. | Better suited for higher-current loads where thermal headroom is critical; not drop-in due to different thermal pad layout in ESV variant. | Select when peak load exceeds 200 mA or ambient exceeds 75°C; verify PCB thermal relief design matches higher PD rating. |
| MCP1700T-1102E/TT | 1.1 V fixed output, 250 mA rating, 6 μA quiescent current, but only 60 dB PSRR at 1 kHz and no auto-discharge function. | Lacks fast transient response (±120 mV typical) and discharge capability-unsuitable for strict power sequencing or RF-sensitive apps. | Choose for ultra-low-IQ battery applications where noise and sequencing are secondary; confirm system-level discharge path exists. |
Compared with TCR2EF11,LM(CT, TCS2EF11,LM(CT offers higher current and thermal margin but requires PCB revision for ESV variants, while MCP1700T-1102E/TT trades off noise performance and sequencing features for extreme quiescent savings-making TCR2EF11,LM(CT optimal for balanced analog/RF power integrity.

FAQ
What is the maximum input voltage rating for TCR2EF11,LM(CT?
The absolute maximum input voltage for TCR2EF11,LM(CT is 6.0 V. However, the recommended operating range is 1.5 V to 5.5 V per the datasheet's Operating Ranges table. Exceeding 5.5 V may trigger overvoltage stress conditions not covered by warranty, and sustained operation above this limit risks permanent damage even if within absolute maximum ratings.
Does TCR2EF11,LM(CT support ceramic output capacitors, and what is the minimum required value?
Yes, TCR2EF11,LM(CT is fully compatible with ceramic output capacitors. The minimum required COUT is 1.0 μF, with ESR less than 10 Ω recommended per Toshiba's Application Note. Using smaller values or higher-ESR types may degrade load transient response and cause instability, as verified in the Load Transient Response test condition (IOUT = 1 mA ⇔ 150 mA).
What is the dropout voltage of TCR2EF11,LM(CT at 150 mA load?
The typical dropout voltage of TCR2EF11,LM(CT at 150 mA output current is 440 mV, as specified in the Dropout Voltage table for 1.1 V output products. This enables stable regulation with input as low as 1.54 V, making it suitable for single-cell Li-ion or multi-cell alkaline systems where headroom is constrained.
How does the CONTROL pin function on TCR2EF11,LM(CT, and what voltage levels define ON/OFF states?
The CONTROL pin on TCR2EF11,LM(CT is an active-high enable input. It drives the regulator into active mode when voltage is 1.0–5.5 V (VCT(ON)), and into shutdown with ≤0.4 V (VCT(OFF)). An internal pull-down ensures default-OFF behavior when left unconnected. Standby current drops to ≤1.0 μA in OFF state, enabling ultra-low-power system sleep modes.
Is TCR2EF11,LM(CT RoHS compliant and lead-free?
Yes, TCR2EF11,LM(CT is RoHS compliant and lead-free, consistent with Toshiba's environmental policy and the "RoHS compatibility" statement in their official documentation. The device meets EU Directive 2011/65/EU requirements, and Pb-free plating is standard on all SMV (SOT-25) and ESV (SOT-553) package variants, including TCR2EF11,LM(CT.
