Product details
Overview
TCR2EE24,LM(CT) from Toshiba Electronic Devices & Storage Corporation is a 2.4 V fixed-output, 200 mA CMOS low dropout regulator with on/off control input, 180 mV dropout (at 150 mA), 35 μVrms output noise, and ±60 mV load transient response (1 mA ⇔ 150 mA). It serves as a precision power supply for analog/RF signal chains in portable instrumentation and wireless modules.
For engineers reviewing the TCR2EE24,LM(CT) datasheet, TCR2EE24,LM(CT) pinout, TCR2EE24,LM(CT) application, or TCR2EE24,LM(CT) equivalent, key selection criteria include dropout voltage at 150 mA, output accuracy (±1.0 % for 2.4 V), ceramic capacitor compatibility (CIN = 0.1 μF, COUT = 1.0 μF), and fast transient response in noise-sensitive LDO applications.
Technical Context
The TCR2EE24,LM(CT) employs a CMOS pass transistor architecture enabling ultra-low quiescent current (35 μA typ.) and high ripple rejection (73 dB at 1 kHz). Its internal control loop is optimized for stability with 1.0 μF ceramic output capacitance and supports auto-discharge via an internal pull-down on the CONTROL pin.
It operates across −40°C to +85°C with input voltage range 1.5–5.5 V and features overcurrent protection plus precise ON/OFF thresholds (VCT(ON) ≥ 1.0 V, VCT(OFF) ≤ 0.4 V), making it suitable for battery-powered systems requiring controlled power sequencing and low standby loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.4 V ±1.0 % (guaranteed accuracy for VOUT ≥ 1.8 V) |
| Max Output Current | 200 mA DC (supports peak loads without thermal shutdown under proper PCB layout) |
| Dropout Voltage | 180 mV typ. at IOUT = 150 mA (enables operation with VIN as low as 2.58 V) |
| Output Noise | 35 μVrms (10 Hz–100 kHz, 2.4 V output) - critical for RF bias and ADC reference supplies |
| Load Transient Response | ±60 mV deviation (1 mA ⇔ 150 mA step, COUT = 1.0 μF) - ensures stable core voltage during digital switching |
| 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
TCR2EE24,LM(CT) 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 placement in space-constrained IoT edge devices and wearable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Power Supply | Accepts 1.5–5.5 V; requires ≥0.1 μF ceramic decoupling close to pin |
| VOUT | Regulated Output | Delivers stable 2.4 V; must connect ≥1.0 μF ceramic capacitor with ESR <10 Ω |
| GND | Ground Reference | Common return path for input/output; requires low-impedance PCB plane connection |
| CONTROL | Enable/Disable Input | Logic-high (≥1.0 V) enables regulation; logic-low (≤0.4 V) disables output and activates auto-discharge |
| NC | No Connect | Internally unconnected; must remain floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | Internal discharge path activates when CONTROL = LOW, rapidly draining VOUT to GND for safe power-down sequencing |
| Ceramic capacitor support | Stable operation with CIN = 0.1 μF and COUT = 1.0 μF (ESR <10 Ω), eliminating need for bulk tantalum or electrolytic caps |
| Low-noise regulation | 35 μVrms output noise enables direct powering of RF transceivers and precision analog front-ends without additional filtering |
| Fast load transient recovery | ±60 mV output deviation during 1 mA ↔ 150 mA load steps ensures minimal voltage droop/surge in mixed-signal SoC supplies |
| Precision output accuracy | ±1.0 % tolerance over temperature and line/load conditions simplifies system-level calibration and improves ADC reference stability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, 200 mA LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2122A-2.4V | Higher dropout (250 mV @ 150 mA); 50 μVrms noise; SOT-23-5 package | Larger footprint; less suitable for ultra-thin wearables | Preferred where board space permits larger package and cost sensitivity outweighs noise/dropout requirements |
| MCP1703T-2402E/MB | Same 2.4 V output; 600 mV dropout @ 250 mA; 40 μVrms noise; SOT-23-5 | Lower max current rating; higher dropout limits usable input range | Valid for non-critical analog rails where 2.4 V accuracy and low noise are secondary to cost and availability |
Compared with TCR2EE24,LM(CT), the TCS2122A-2.4V trades lower noise performance for broader vendor availability, while the MCP1703T-2402E/MB offers legacy compatibility but sacrifices dropout efficiency and transient response-making TCR2EE24,LM(CT) optimal for space-constrained, noise-sensitive 2.4 V analog/RF power domains.

FAQ
What is the guaranteed output voltage accuracy of TCR2EE24,LM(CT) over temperature and load?
The TCR2EE24,LM(CT) guarantees ±1.0 % output voltage accuracy for VOUT ≥ 1.8 V across −40°C to +85°C operating temperature and 1 mA to 150 mA load range. This specification is validated per Toshiba's Electrical Characteristics table (Note 6), ensuring consistent 2.4 V regulation in precision analog circuits without external trimming.
Can TCR2EE24,LM(CT) operate with only ceramic capacitors, and what are the minimum values?
Yes, TCR2EE24,LM(CT) is fully compatible with ceramic capacitors: minimum CIN = 0.1 μF and COUT = 1.0 μF. Toshiba specifies ESR <10 Ω for COUT to ensure phase margin and transient stability. The device's internal compensation eliminates need for electrolytic or tantalum types, reducing board area and improving reliability.
What is the CONTROL pin behavior and how does auto-discharge work in TCR2EE24,LM(CT)?
The CONTROL pin enables (HIGH ≥1.0 V) or disables (LOW ≤0.4 V) regulation. When disabled, TCR2EE24,LM(CT) activates an internal discharge path between VOUT and GND, rapidly collapsing output voltage. This feature supports safe power sequencing in multi-rail systems and prevents back-powering of upstream circuitry during shutdown.
What is the maximum allowable input voltage and thermal limit for continuous operation of TCR2EE24,LM(CT)?
TCR2EE24,LM(CT) supports VIN up to 6.0 V absolute maximum, but recommended operating range is 1.5–5.5 V. Junction temperature must not exceed 150°C. At 200 mA load, thermal design must respect ESV package power dissipation ratings: 150 mW (unit) or 320 mW (on 30 mm × 30 mm × 0.8 mm FR4 board), per Toshiba's Absolute Maximum Ratings table.
How does the load transient response of TCR2EE24,LM(CT) compare to standard LDOs, and what enables its performance?
TCR2EE24,LM(CT) achieves ±60 mV output deviation during 1 mA ↔ 150 mA load steps-significantly tighter than typical 100–200 mV for general-purpose LDOs. This is enabled by a high-gain, fast-response CMOS control loop optimized for 1.0 μF ceramic output capacitance, minimizing recovery time and overshoot in dynamic digital loads.
