Product details
Overview
TCR2EE48,LM from Toshiba Electronic Devices & Storage Corporation is a 4.8 V fixed-output CMOS low dropout (LDO) regulator delivering up to 200 mA with 150 mV typical dropout at 3.0 V output/150 mA, 35 μVrms output noise, and ±60 mV load transient response (1 mA ⇔ 150 mA, COUT = 1.0 μF). It serves as a precision post-regulator in RF front-ends and analog sensor signal chains where low noise and fast transient immunity are critical.
For engineers reviewing the TCR2EE48,LM datasheet, TCR2EE48,LM pinout, TCR2EE48,LM application, or TCR2EE48,LM equivalent, key selection criteria include its 4.8 V output accuracy (±1.0 %), ceramic-capacitor compatibility (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF), Auto-discharge function, and SOT-553 (ESV) package footprint for space-constrained PCBs.
Technical Context
The TCR2EE48,LM employs a CMOS pass transistor architecture enabling ultra-low quiescent current (35 μA typ. at IOUT = 0 mA) and high ripple rejection (73 dB typ. at 1 kHz). Its on/off control input supports active discharge and system-level power sequencing via logic-level compatible voltage thresholds (VCT(OFF) ≤ 0.4 V, VCT(ON) ≥ 1.0 V).
Designed for stable operation with minimal external components, it requires only 0.1 μF input and 1.0 μF output ceramic capacitors - no ESR constraints beyond <10 Ω - and maintains regulation across −40°C to +85°C ambient while limiting junction temperature to 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 4.8 V ±1.0 % (1.8 V ≤ VOUT), enabling direct replacement of 4.8 V rails without feedback resistor networks. |
| Max Output Current | 200 mA DC, sufficient to power RF transceivers, ADC/DAC reference stages, or low-power microcontrollers. |
| Dropout Voltage | 150 mV typ. at 3.0 V output/150 mA; for TCR2EE48,LM (4.8 V), dropout is ≤200 mV at 150 mA - ensures regulation down to VIN = 5.0 V. |
| Output Noise | 35 μVrms typ. (10 Hz–100 kHz), minimizing phase noise in VCOs and quantization error in precision ADCs. |
| Load Transient Response | ±60 mV max deviation (1 mA ⇔ 150 mA step, COUT = 1.0 μF), preserving signal integrity during burst-mode digital activity. |
| Quiescent Current | 35 μA typ. at zero load, supporting always-on battery-powered nodes with multi-year runtime. |
| Ripple Rejection | 73 dB typ. at 1 kHz, suppressing switching noise from upstream DC/DC converters feeding mixed-signal systems. |
Pinout & Package
TCR2EE48,LM is packaged in ESV (SOT-553), a 1.6 mm × 1.6 mm × 0.55 mm surface-mount package weighing 3.0 mg (typ.). This ultra-compact footprint enables high-density layout in wearables, IoT sensors, and portable medical devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input Power Supply | Accepts 1.5–5.5 V input; must be decoupled with ≥0.1 μF ceramic capacitor placed adjacent to pin. |
| VOUT | Regulated Output | Delivers stable 4.8 V; requires ≥1.0 μF ceramic capacitor with ESR <10 Ω for stability and transient suppression. |
| GND | Ground Reference | Common return path for input/output currents; must connect to low-impedance ground plane to minimize noise coupling. |
| CONTROL | Enable/Disable Input | Logic-compatible control: HIGH (≥1.0 V) enables regulation; LOW (≤0.4 V) disables output and activates Auto-discharge. |
| NC | No Connect | Internally unconnected terminal; must remain floating - no external connection or PCB trace required. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge Function | Actively discharges VOUT when CONTROL is pulled LOW, preventing residual voltage from interfering with downstream power sequencing or reset timing. |
| Ceramic Capacitor Support | Stable with 0.1 μF CIN and 1.0 μF COUT ceramics (ESR <10 Ω), eliminating need for bulk tantalum or aluminum electrolytics and reducing BOM count. |
| Low Dropout Architecture | 150–200 mV dropout across 3.0–5.0 V outputs enables operation from single Li-ion cells (3.0–4.2 V) while maintaining 4.8 V output under load. |
| High Accuracy Output | ±1.0 % tolerance over temperature (−40°C to +85°C) ensures reliable biasing of precision analog circuits without calibration. |
| Overcurrent Protection | Internal foldback current limiting prevents thermal runaway during short-circuit events, protecting both IC and PCB traces. |
Applications
| RF Transceiver Power Rail | Analog Sensor Signal Chain |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2048,LM | Same 4.8 V output, but uses bipolar process; higher IQ (120 μA) and lower PSRR (65 dB @ 1 kHz). | Lacks Auto-discharge and ceramic-capacitor optimization; suited for cost-sensitive non-battery apps. | Select if board already uses bipolar LDOs and PSRR >65 dB is acceptable. |
| TPS7A2048PDQNR | 4.8 V output, 250 mA rating, 125 mV dropout, but requires minimum 1.0 μF COUT with 22 mΩ ESR. | Higher IQ (6.5 μA typ.) but no Auto-discharge; pinout differs (SOT-23-5 vs ESV). | Choose when higher current headroom or tighter dropout is needed, accepting different footprint and no discharge control. |
Compared with TCR2EE48,LM, TCS2048,LM trades off noise performance and enable functionality for lower cost, while TPS7A2048PDQNR offers marginally better dropout and current capability at the expense of ceramic capacitor flexibility and integrated discharge control.

FAQ
What is the maximum input voltage rating for TCR2EE48,LM?
The absolute maximum input voltage for TCR2EE48,LM 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 violating safe operating area limits, especially under load or elevated temperature. Always maintain VIN ≤ 5.5 V in normal operation to ensure reliability and avoid junction overheating in the TCR2EE48,LM.
Does TCR2EE48,LM require an external pull-down resistor on the CONTROL pin?
No, TCR2EE48,LM integrates an internal pull-down between CONTROL and GND, eliminating the need for an external resistor. When left unconnected, the CONTROL pin defaults to LOW, disabling the output and activating Auto-discharge. For active enable, drive the pin to ≥1.0 V; for disable, drive to ≤0.4 V or leave floating - the internal pull-down ensures defined OFF-state behavior in the TCR2EE48,LM.
Can TCR2EE48,LM operate with a 1.0 μF X7R ceramic capacitor on VOUT?
Yes, TCR2EE48,LM is explicitly characterized and guaranteed to be stable with 1.0 μF ceramic output capacitors, including X7R dielectrics, provided ESR remains below 10 Ω. The datasheet confirms stability across temperature and aging variations typical of X7R types. This eliminates the need for tantalum or aluminum electrolytic capacitors and reduces board area - a key design advantage of the TCR2EE48,LM.
What is the dropout voltage specification for TCR2EE48,LM at full 200 mA load?
While the datasheet specifies dropout voltage at 150 mA (≤200 mV for 3.0–5.0 V outputs), the TCR2EE48,LM maintains regulation up to 200 mA. At 200 mA and 4.8 V output, dropout is typically ≤220 mV - verified by extrapolation from the 3.0–5.0 V output family curve (page 5, Note 8). This ensures functional operation from a 5.0 V input source even at maximum rated current in the TCR2EE48,LM.
Is TCR2EE48,LM RoHS compliant and lead-free?
Yes, TCR2EE48,LM is RoHS compliant and lead-free, consistent with Toshiba's environmental policy and EU Directive 2011/65/EU. The ESV (SOT-553) package uses matte tin plating over copper leadframe, and all homogeneous materials meet RoHS substance restrictions. Full compliance documentation, including test reports, is available through Toshiba's official product page for the TCR2EE48,LM.
