Product details
Overview
TCR2EE50,LM from Toshiba Electronic Devices & Storage Corporation is a 5.0 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 150 mV typical dropout at full load, 35 μVrms output noise, and ±60 mV load transient response-designed for analog/RF power rails in portable instrumentation and wireless modules.
For engineers reviewing the TCR2EE50,LM datasheet, TCR2EE50,LM pinout, TCR2EE50,LM application, or TCR2EE50,LM equivalent, this device offers verified fast transient performance, ±1.0% output accuracy above 1.8 V, ceramic capacitor compatibility (CIN = 0.1 μF, COUT = 1.0 μF), and on/off control with auto-discharge functionality.
Technical Context
The TCR2EE50,LM implements a CMOS-based LDO architecture with integrated overcurrent protection and an active pull-down circuit on the CONTROL pin. Its low quiescent current (35 μA typ.) and high ripple rejection (73 dB at 1 kHz) support battery-powered precision analog systems.
It operates across −40°C to +85°C with input voltage range 1.5–5.5 V and requires no external compensation. The device supports stable regulation with ceramic output capacitors down to 1.0 μF and features auto-discharge via internal NMOS discharge path when disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±1.0% (guaranteed accuracy for stable reference-sensitive loads) |
| Max Output Current | 200 mA DC (supports moderate-power analog ICs and RF front-ends) |
| Dropout Voltage | 150 mV typ. at IOUT = 150 mA (enables operation with VIN as low as 5.15 V) |
| Output Noise | 35 μVrms typ. (10 Hz–100 kHz) - preserves SNR in ADCs and RF synthesizers |
| Load Transient Response | ±60 mV max ΔVOUT (1 mA ↔ 150 mA step, COUT = 1.0 μF) |
| Quiescent Current | 35 μA typ. at zero load - extends battery life in always-on sensor nodes |
| Ripple Rejection | 73 dB typ. at 1 kHz - suppresses switching noise from upstream DC/DC converters |
Pinout & Package
TCR2EE50,LM is packaged in ESV (SOT-553), a 1.6 mm × 1.6 mm × 0.55 mm ultra-small surface-mount package weighing 3.0 mg (typ.). This footprint enables high-density PCB layouts in space-constrained IoT and wearable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input supply connection | Accepts 1.5–5.5 V; requires ≥0.1 μF ceramic bypass capacitor |
| VOUT | Regulated output | Delivers stable 5.0 V; requires ≥1.0 μF ceramic output capacitor for stability |
| GND | Ground reference | Common return for input, output, and control circuits; must be low-impedance |
| CONTROL | Enable/disable input | Active-high logic: ≥1.0 V turns ON; ≤0.4 V disables with auto-discharge activation |
| NC | No-connect terminal | Internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Fast load transient response | ±60 mV output deviation during 1 mA ↔ 150 mA load steps - minimizes voltage droop in burst-mode RF transceivers |
| Auto-discharge function | Internal NMOS discharges VOUT when CONTROL = LOW - prevents residual voltage hold-up in power sequencing |
| Ceramic capacitor compatibility | Stable with CIN = 0.1 μF and COUT = 1.0 μF - eliminates need for bulk tantalum or electrolytic capacitors |
| Low quiescent current | 35 μA typ. at zero load - enables >1-year battery life in low-duty-cycle sensor nodes |
| High output accuracy | ±1.0% tolerance for VOUT ≥ 1.8 V - ensures reliable operation of 5 V-tolerant microcontrollers and interface ICs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2050EUS | Same 5.0 V output, but 300 mA rating and higher 250 mV dropout at 150 mA | Better suited for higher-current peripherals; less optimal for ultra-low-noise analog use | Choose when higher output current margin is required and noise <35 μVrms is not critical |
| MCP1700T-5002E/MB | 5.0 V output, 250 mA, 6 μA quiescent current, but ±2% accuracy and no auto-discharge | Lowers standby power significantly but lacks fast transient response (±120 mV) and discharge control | Prefer for ultra-low-power always-on sensors where discharge sequencing is handled externally |
Compared with TCR2EE50,LM, TCS2050EUS trades lower noise and tighter accuracy for higher current capability, while MCP1700T-5002E/MB reduces quiescent current by >80% but sacrifices transient performance and active discharge-making TCR2EE50,LM optimal for noise-sensitive, sequenced 5 V analog/RF rails.

FAQ
What is the maximum input voltage rating for TCR2EE50,LM?
The absolute maximum input voltage for TCR2EE50,LM is 6.0 V. However, the 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 ratings, potentially degrading long-term reliability. Always maintain VIN ≤ 5.5 V in normal operation to ensure compliance with specified electrical characteristics and thermal limits.
Does TCR2EE50,LM require an external resistor for the CONTROL pin?
No, TCR2EE50,LM does not require an external pull-up or pull-down resistor on the CONTROL pin. It features an internal pull-down connection between CONTROL and GND. The pin accepts 0–5.5 V logic levels: voltage ≥1.0 V enables regulation, while ≤0.4 V disables it and activates the auto-discharge function. External resistors are unnecessary unless specific timing or noise immunity requirements dictate otherwise.
Can TCR2EE50,LM operate with a 1.0 μF ceramic output capacitor only?
Yes, TCR2EE50,LM is fully stable with a single 1.0 μF X5R/X7R ceramic capacitor at VOUT, as confirmed in Toshiba's Electrical Characteristics table and Application Note. No additional ESR requirements or parallel capacitors are needed. The device's internal compensation is optimized for ceramic capacitors with ESR <10 Ω, making it compatible with standard 0603/0805 MLCCs commonly used in space-constrained designs.
What is the dropout voltage of TCR2EE50,LM at 200 mA load?
The dropout voltage of TCR2EE50,LM is specified up to 150 mA in the datasheet (150 mV typ. at 3.0–5.0 V outputs). At 200 mA-the absolute maximum rated output current-the dropout increases beyond guaranteed specs; Toshiba does not characterize or guarantee performance at 200 mA. For reliable operation, design with IOUT ≤ 150 mA to ensure 150 mV typical dropout and maintain ±1.0% accuracy and thermal safety margins.
Is TCR2EE50,LM pin-compatible with other TCR2EE series variants?
Yes, all TCR2EE series devices-including TCR2EE50,LM-share identical ESV (SOT-553) pinout and footprint: VIN, VOUT, GND, CONTROL, NC in the same top-view order. This allows direct substitution across output voltages (1.0–5.0 V) without PCB redesign. However, note that electrical behavior (e.g., dropout, noise, accuracy) varies per VOUT variant, so functional validation remains essential despite mechanical compatibility.
