Product details
Overview
TCR2EF13,LM(CT) from Toshiba Electronic Devices & Storage Corporation is a 1.3 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 350 mV typical dropout voltage at 150 mA 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 TCR2EF13,LM(CT) datasheet, TCR2EF13,LM(CT) pinout, TCR2EF13,LM(CT) application, or TCR2EF13,LM(CT) equivalent, key selection criteria include dropout performance at 1.3 V output, fast transient behavior under 1 mA–150 mA step loads, ceramic capacitor compatibility (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF), and SMV (SOT-25) package thermal limits.
Technical Context
The TCR2EF13,LM(CT) employs a CMOS pass transistor architecture enabling low quiescent current (35 μA typ.) and high ripple rejection (73 dB typ. at 1 kHz). Its on/off control input supports active discharge via internal pull-down when CONTROL is low, ensuring rapid output discharge during shutdown.
It operates across −40°C to +85°C with ±1.0% output accuracy for VOUT ≥ 1.8 V; for 1.3 V output, accuracy is specified as ±18 mV. Dropout voltage is confirmed at 350 mV (typ.) and 470 mV (max) under 150 mA load per datasheet Table 5.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.3 V ±18 mV - enables stable biasing of 1.3 V logic or analog circuitry without external feedback. |
| Dropout voltage | 350 mV (typ.) at IOUT = 150 mA - allows operation from 1.65 V input, supporting single-cell LiFePO₄ or dual-cell alkaline supplies. |
| Output noise | 35 μVrms (typ., 10 Hz–100 kHz) - minimizes phase noise in RF local oscillators and ADC reference paths. |
| Load transient response | ±60 mV (typ., 1 mA ⇔ 150 mA, COUT = 1.0 μF) - maintains regulation during burst-mode MCU or transceiver current spikes. |
| Quiescent current | 35 μA (typ., IOUT = 0 mA) - extends battery life in always-on IoT endpoints with infrequent wake-up cycles. |
| Ripple rejection | 73 dB (typ., 1 kHz, 2.5 V output) - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Operating temperature | −40°C to +85°C - qualified for industrial-grade embedded systems and automotive cabin electronics. |
Pinout & Package
TCR2EF13,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 1 is VOUT, Pin 2 is GND, Pin 3 is CONTROL, Pin 4 is NC (no connect), and Pin 5 is VIN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT (Pin 1) | Regulated output | Delivers stable 1.3 V to load; requires ≥1.0 μF ceramic capacitor to ground for stability. |
| GND (Pin 2) | Power ground reference | Common return path for input, output, and control circuits; must be low-impedance and adjacent to VIN/VOUT caps. |
| CONTROL (Pin 3) | Enable/disable input | Drives regulator ON when ≥1.0 V; forces shutdown and auto-discharge when ≤0.4 V; internally pulled down to GND. |
| NC (Pin 4) | No connect | Not bonded; must remain unconnected and unrouted to avoid parasitic coupling or mechanical stress. |
| VIN (Pin 5) | Input supply | Accepts 1.5–5.5 V; requires ≥0.1 μF ceramic decoupling capacitor placed near this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout voltage | 350 mV typ. at 150 mA ensures usable headroom from low-voltage batteries (e.g., 1.65 V min input for 1.3 V out). |
| Auto-discharge function | Internal discharge path activates when CONTROL = LOW, reducing VOUT to <0.1 V within microseconds - critical for safe 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 circuit prevents damage during short-circuit or overload events; output folds back to limit power dissipation. |
| High accuracy at low VOUT | ±18 mV tolerance at 1.3 V enables precise biasing of low-voltage analog sensors and reference buffers without trimming. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2EF13,LM(CT) | Same pinout and electrical specs but uses different process; 100 ppm/°C tempco vs. 100 ppm/°C (identical); same 350 mV dropout at 150 mA. | No functional difference; identical qualification and marking - suitable for second-source procurement only. | Select when dual-sourcing is required and board layout reuse is mandatory. |
| MCP1700T-1302E/TT | 1.3 V fixed, 250 mA, 600 mV dropout (typ. at 250 mA); higher quiescent current (1.6 μA vs. 35 μA); no auto-discharge. | Lacks active discharge and has slower transient response (±120 mV); better suited for non-sequenced, low-cost consumer applications. | Choose only if auto-discharge and fast transient are not required and cost is primary constraint. |
Compared with TCR2EF13,LM(CT), TCS2EF13,LM(CT) offers identical performance and drop-in compatibility, while MCP1700T-1302E/TT trades off transient performance and sequencing capability for lower unit cost and wider input range (2.3–6.0 V).

FAQ
What is the maximum input voltage rating for TCR2EF13,LM(CT)?
The absolute maximum input voltage for TCR2EF13,LM(CT) is 6.0 V. Continuous operation above 5.5 V violates the recommended operating range and risks permanent damage. The device is rated for 1.5–5.5 V input during normal operation, making it compatible with standard 3.3 V or 5 V supply rails and single-cell Li-ion/LiFePO₄ sources. Always observe derating guidelines per Toshiba Semiconductor Reliability Handbook.
Does TCR2EF13,LM(CT) require an external resistor for output voltage setting?
No, TCR2EF13,LM(CT) is a fixed-output LDO with factory-trimmed 1.3 V regulation - no external resistors or feedback network is needed. Its output voltage is laser-trimmed during production and specified as ±18 mV over temperature and load. This eliminates component count and layout complexity compared to adjustable regulators, improving system reliability and reducing bill-of-materials cost.
Can TCR2EF13,LM(CT) be used with ceramic output capacitors?
Yes, TCR2EF13,LM(CT) is fully compatible with ceramic output capacitors. The datasheet explicitly states COUT ≥ 1.0 μF ceramic (ESR <10 Ω) ensures stability. Unlike older LDO architectures, its CMOS design does not require minimum ESR, enabling compact, low-ESR, high-reliability ceramic solutions instead of bulkier tantalum or aluminum electrolytic capacitors.
What happens to the output when the CONTROL pin is left floating?
When the CONTROL pin is left floating, TCR2EF13,LM(CT) enters shutdown mode due to its internal pull-down connection to GND. This forces the output to discharge rapidly via the auto-discharge function, bringing VOUT to <0.1 V within microseconds. To enable regulation, CONTROL must be actively driven to ≥1.0 V; open-circuit or high-impedance states are not valid operating conditions.
Is thermal derating required for TCR2EF13,LM(CT) in high-ambient environments?
Yes, thermal derating is required. At 25°C ambient, SMV-package TCR2EF13,LM(CT) supports up to 200 mW unit-rated power dissipation, but this drops linearly with rising temperature - e.g., ~120 mW at 60°C ambient. For continuous 200 mA output at 1.3 V with 2.5 V input (1.2 V dropout), power dissipation is 240 mW - exceeding ratings unless board-level thermal management (e.g., 25.4 mm × 25.4 mm FR4 with 645 mm² copper) is implemented per Note 2 in Absolute Maximum Ratings.
