Product details
Overview
TCR2EE33,LM from Toshiba Electronic Devices & Storage Corporation is a 3.3 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 powering sensitive analog and RF circuitry in portable and space-constrained systems.
For engineers reviewing the TCR2EE33,LM datasheet, TCR2EE33,LM pinout, TCR2EE33,LM application, or TCR2EE33,LM equivalent, this device offers verified fast transient performance, ±1.0% output accuracy (≥1.8 V), ceramic capacitor compatibility (CIN = 0.1 μF, COUT = 1.0 μF), and on/off control with auto-discharge - critical for battery-powered IoT sensors and RF front-end biasing.
Technical Context
The TCR2EE33,LM 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 minimal external capacitance, supporting fast recovery from 1 mA ↔ 150 mA load steps without external compensation.
It integrates overcurrent protection and an active pull-down on the CONTROL pin (0–0.4 V OFF threshold), ensuring reliable shutdown and automatic discharge of output capacitance when disabled - essential for power sequencing in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.3 V ±1.0% (guaranteed over −40°C to +85°C, 1 mA–150 mA load) |
| Dropout voltage | 150 mV typ. at IOUT = 150 mA - enables operation from 3.45 V input, ideal for single-cell Li-ion or 3.6 V supply rails |
| Output noise | 35 μVrms (10 Hz–100 kHz) - low enough for RF LNA and ADC reference supplies without additional filtering |
| Load transient response | ±60 mV max deviation for 1 mA ↔ 150 mA step (COUT = 1.0 μF) - maintains signal integrity during burst-mode wireless transmission |
| Quiescent current | 35 μA typ. at zero load - extends battery life in always-on sensor nodes and wearables |
| Ripple rejection | 73 dB typ. at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding mixed-signal subsystems |
| Operating input range | 1.5 V to 5.5 V - supports wide-input applications including USB-powered and industrial 3.3/5 V systems |
Pinout & Package
TCR2EE33,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.), optimized for high-density PCB layouts in portable 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 3.3 V; must be bypassed with ≥1.0 μF ceramic capacitor for transient stability |
| GND | Ground reference | Common return path for input, output, and control circuits; low-impedance layout required |
| CONTROL | Enable/disable input | Active-high logic: ≥1.0 V enables regulation; ≤0.4 V disables output and activates auto-discharge |
| NC | No connect | Internally unconnected; must remain floating or grounded per layout best practice (not used) |
Key Features
| Feature | Design Value |
|---|---|
| Fast load transient response | ±60 mV output deviation for 1 mA ↔ 150 mA load step - minimizes voltage droop during RF transmit bursts |
| Auto-discharge function | Actively discharges VOUT when CONTROL = LOW - prevents residual voltage from interfering with system reset or sequencing |
| Ceramic capacitor compatibility | Stable with 0.1 μF CIN and 1.0 μF COUT - eliminates need for bulk tantalum or electrolytic capacitors, reducing board area and cost |
| Low-noise regulation | 35 μVrms integrated noise - avoids adding jitter to clock buffers or degrading SNR in precision ADCs |
| High accuracy output | ±1.0% tolerance over temperature and load - ensures consistent biasing for amplifiers and references without calibration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCS2003B33 | Higher 250 mV dropout at 200 mA; 50 μVrms noise; no auto-discharge | Lacks fast transient response (±120 mV) and active discharge - unsuitable for burst-mode RF or strict sequencing | Choose only if footprint compatibility with SMV package is required and discharge control is handled externally |
| XC6219B332MR-G | Same 3.3 V output, 120 mV dropout, but 60 μA quiescent current and no CONTROL pin | Fixed-on operation only; no enable/disable control - limits use in power-gated subsystems | Select when simple always-on regulation suffices and lowest possible dropout is prioritized over control flexibility |
Compared with TCR2EE33,LM, TCS2003B33 trades transient performance and discharge control for legacy package compatibility, while XC6219B332MR-G sacrifices enable functionality and quiescent efficiency for marginally lower dropout - making TCR2EE33,LM optimal for space-constrained, controllable, low-noise applications.

FAQ
What is the maximum input voltage rating for TCR2EE33,LM?
The absolute maximum input voltage for TCR2EE33,LM is 6.0 V. However, the recommended operating input range is 1.5 V to 5.5 V. Exceeding 5.5 V may trigger overvoltage stress beyond design specifications, even if within absolute maximum ratings - sustained operation above 5.5 V is not guaranteed and risks reliability degradation. Always refer to the Electrical Characteristics table for valid VIN conditions.
Does TCR2EE33,LM require an external resistor on the CONTROL pin?
No, TCR2EE33,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, and the pin accepts standard CMOS logic levels: ≥1.0 V enables regulation, ≤0.4 V disables it and activates auto-discharge. External resistors are unnecessary unless specific timing or noise immunity requirements dictate otherwise.
Can TCR2EE33,LM be used with aluminum polymer capacitors instead of ceramic?
TCR2EE33,LM is characterized and guaranteed for stability with ceramic capacitors (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF). While aluminum polymer capacitors may function in some cases, their higher ESR and different frequency response can compromise transient performance and phase margin. Toshiba explicitly recommends ceramic types and specifies ESR < 10 Ω - using non-ceramic capacitors voids stability guarantees and may cause oscillation or excessive overshoot.
What is the thermal resistance (θJA) of TCR2EE33,LM in the ESV package?
TCR2EE33,LM in the ESV (SOT-553) package has a board-mounted thermal resistance (θJA) of approximately 220°C/W when mounted on a 30 mm × 30 mm × 0.8 mm FR4 board with 20 mm² copper area. This value is derived from its 150 mW unit power dissipation rating and 320 mW board-mounted rating. For accurate junction temperature estimation, use θJA = (TJ − TA) / PD, with TJ ≤ 150°C.
Is TCR2EE33,LM pin-compatible with TCR2EF33?
Yes, TCR2EE33 and TCR2EF33 share identical pinout (ESV/SOT-553 and SMV/SOT-25), electrical specifications, and functional behavior. The primary distinction is marking and minor process-level optimizations - both are drop-in replacements in layout and schematic. No PCB changes are required when substituting TCR2EE33 for TCR2EF33 or vice versa, provided the same package variant is selected.
