Product details
Overview
TCR2EE32,LM(CT from Toshiba Electronic Devices & Storage Corporation is a 3.2 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 150 mV typical dropout voltage at full load, 35 μVrms output noise, and ±60 mV load transient response-designed for analog/RF power rails in portable instrumentation and wireless sensor nodes.
For engineers reviewing the TCR2EE32,LM(CT datasheet, TCR2EE32,LM(CT pinout, TCR2EE32,LM(CT application, or TCR2EE32,LM(CT equivalent, this page delivers verified electrical specs, package mapping to SOT-553 (ESV), on/off control interface behavior, and real-world design implications for low-noise, fast-transient power delivery.
Technical Context
The TCR2EE32,LM(CT integrates a CMOS pass transistor with internal reference and error amplifier to achieve ultra-low quiescent current (35 μA typ.) and high ripple rejection (73 dB at 1 kHz). Its Auto-discharge function actively discharges the output capacitor when disabled via CONTROL pin, preventing residual voltage hold-up in battery-powered systems.
It operates across −40°C to +85°C with ±1.0% output accuracy for VOUT ≥ 1.8 V and supports ceramic input/output capacitors (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF). The CONTROL pin accepts 0–0.4 V for OFF and 1.0–5.5 V for ON, enabling direct interfacing with MCU GPIOs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.2 V ±1.0% (ensures stable biasing for 3.3 V-tolerant analog ICs without external feedback) |
| Max output current | 200 mA DC (supports moderate-power RF transceivers or multi-channel ADCs) |
| Dropout voltage | 150 mV typ. at IOUT = 150 mA (enables operation down to VIN = 3.35 V, critical for single-cell Li-ion or coin-cell systems) |
| Output noise | 35 μVrms (10 Hz–100 kHz) (minimizes phase noise in VCOs and SNR degradation in precision ADCs) |
| Ripple rejection | 73 dB typ. at 1 kHz (suppresses switching noise from upstream DC/DC converters feeding the LDO) |
| Quiescent current | 35 μA typ. at zero load (extends battery life in always-on sensor nodes) |
| Control logic | Active-high CONTROL pin (1.0–5.5 V ON / 0–0.4 V OFF) with 0.1 μA standby current (enables precise power sequencing) |
Pinout & Package
TCR2EE32,LM(CT uses the ESV (SOT-553) package: 1.6 mm × 1.6 mm × 0.55 mm, 5-pin surface-mount, weight 3.0 mg (typ.).
| 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 |
| VOUT | Regulated output | Delivers fixed 3.2 V; requires ≥1.0 μF ceramic capacitor with ESR <10 Ω for transient response and PSRR |
| GND | Power ground reference | Must be low-impedance plane; shared return path for VIN, VOUT, and CONTROL to minimize noise coupling |
| CONTROL | Enable/disable logic input | CMOS-compatible; pulls down internally when open; drives device into 0.1 μA shutdown state when ≤0.4 V |
| NC | No-connect terminal | Not bonded; must remain unconnected per Toshiba design-no routing or grounding allowed |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | Internally connects VOUT to GND via 200 Ω resistor when CONTROL = LOW, fully discharging COUT within ~10 ms (critical for safe power-down in medical wearables) |
| Ceramic capacitor compatibility | Stable with CIN = 0.1 μF and COUT = 1.0 μF ceramics (eliminates need for costly tantalum or electrolytic caps, reducing BOM cost and board area) |
| Fast load transient response | ±60 mV output deviation during 1 mA ↔ 150 mA step load (maintains clean supply for burst-mode RF transmission without external compensation) |
| Low dropout architecture | 150 mV dropout at 150 mA enables >95% efficiency at VIN = 3.35 V → 3.2 V conversion (maximizes runtime in energy-constrained IoT edge devices) |
| High accuracy over temperature | ±1.0% output tolerance from −40°C to +85°C (reduces calibration overhead in industrial sensor signal chains) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2EF32,LM(CT | Same TCR2xx family, SMV (SOT-25) package (2.8 mm × 2.9 mm); 16 mg weight vs. 3.0 mg; higher thermal resistance | Better heat dissipation at high ambient temps (>70°C); larger footprint limits ultra-compact designs | Select when board space permits and thermal margin is prioritized over miniaturization |
| MCP1703T-3202E/MB | Microchip 3.2 V LDO; 250 mV dropout at 250 mA; 65 μVrms noise; no Auto-discharge; SOT-23-5 package | Lacks active discharge-requires external circuitry for rapid VOUT decay; higher noise impacts sensitive analog stages | Choose only if Auto-discharge is unnecessary and board already uses Microchip ecosystem |
Compared with TCR2EE32,LM(CT, the TCS2EF32,LM(CT offers identical electrical performance in a larger, thermally robust package, while the MCP1703T-3202E/MB trades off noise, dropout, and discharge capability for broader vendor support-making TCR2EE32,LM(CT optimal for size- and noise-critical portable analog/RF systems.

FAQ
What is the maximum input voltage rating for TCR2EE32,LM(CT?
The absolute maximum input voltage for TCR2EE32,LM(CT is 6.0 V. However, the recommended operating range is 1.5 V to 5.5 V per the datasheet. Exceeding 5.5 V risks permanent damage even if duration is brief, and operation above 6.0 V violates absolute maximum ratings. Always maintain VIN ≤ 5.5 V in normal use to ensure reliability and warranty coverage for TCR2EE32,LM(CT.
Does TCR2EE32,LM(CT require an external pull-up resistor on the CONTROL pin?
No, TCR2EE32,LM(CT does not require an external pull-up resistor on the CONTROL pin. It features an internal pull-down connection between CONTROL and GND, ensuring default OFF state when the pin is left floating. Driving CONTROL to ≥1.0 V enables regulation; pulling it to ≤0.4 V disables output and activates Auto-discharge. This simplifies interface design with microcontrollers lacking dedicated enable pins.
Can TCR2EE32,LM(CT operate with a 1.0 μF ceramic output capacitor having 20 Ω ESR?
No-TCR2EE32,LM(CT requires the ESR of the 1.0 μF ceramic output capacitor to be under 10 Ω, as specified in Toshiba's Application Note. A 20 Ω ESR exceeds this limit and may cause instability, excessive overshoot during load transients, or oscillation. Use X5R/X7R ceramics rated for low-ESR operation and verify impedance profile across frequency before finalizing layout for TCR2EE32,LM(CT.
What is the thermal performance difference between TCR2EE32,LM(CT in ESV vs. SMV packages?
TCR2EE32,LM(CT in ESV (SOT-553) has lower thermal mass (3.0 mg vs. 16 mg) but reduced board-mounted power dissipation: 150 mW unit rating and 320 mW on a 30 mm × 30 mm × 0.8 mm FR4 board. In contrast, the SMV (SOT-25) variant supports 200 mW unit and 580 mW board rating. Thus, ESV suits compact, low-power designs (<150 mW dissipation), while SMV is preferred for higher ambient temperatures or sustained 200 mA loads where thermal margin is critical for TCR2EE32,LM(CT.
Is TCR2EE32,LM(CT RoHS compliant and halogen-free?
Yes, TCR2EE32,LM(CT meets EU RoHS Directive requirements and is halogen-free per Toshiba's environmental compliance documentation. Full material declarations and test reports are available through Toshiba's official portal or authorized distributors. For high-reliability applications subject to strict environmental audits, confirm latest status via Toshiba's website or contact Aetrix Electronics for certified compliance documentation specific to TCR2EE32,LM(CT lot numbers.
