Toshiba Semiconductor and Storage TCR2EE29,LM(CT

Overview

TCR2EE29,LM(CT) from Toshiba Electronic Devices & Storage Corporation is a 2.9 V fixed-output CMOS low dropout regulator delivering up to 200 mA with 180 mV dropout (at 150 mA), 35 μVrms output noise, and ±60 mV load transient response (1 mA ⇔ 150 mA, COUT = 1.0 μF). It features on/off control, overcurrent protection, auto-discharge, and supports ceramic input/output capacitors (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF) in the ESV (SOT-553) package for space-constrained analog and RF power rails.

For engineers reviewing the TCR2EE29,LM(CT) datasheet, TCR2EE29,LM(CT) pinout, TCR2EE29,LM(CT) application, or TCR2EE29,LM(CT) equivalent, key selection criteria include dropout voltage at 150 mA, output accuracy (±1.0% for 2.9 V), quiescent current (35 μA typ.), ripple rejection (73 dB at 1 kHz), and compatibility with 0.1 μF/1.0 μF ceramic capacitors in SOT-553 footprint.

Technical Context

The TCR2EE29,LM(CT) employs a CMOS-based LDO architecture with integrated P-channel pass transistor, enabling low dropout and fast transient recovery via internal compensation optimized for 1.0 μF ceramic output capacitance. Its control logic accepts 0–0.4 V for OFF and 1.0–5.5 V for ON states, with auto-discharge activated when CONTROL is pulled low.

It operates across −40°C to +85°C with input voltage range 1.5–5.5 V, supports stable regulation down to 1.0 V output, and maintains ±1.0% output accuracy for VOUT ≥ 1.8 V - directly applicable to the 2.9 V nominal output of TCR2EE29,LM(CT). Thermal performance is rated for 150 mW unit dissipation and 320 mW board-mounted (FR4, 30 mm × 30 mm × 0.8 mm).

FAQ

What is the maximum input voltage rating for TCR2EE29,LM(CT)?

The absolute maximum input voltage for TCR2EE29,LM(CT) is 6.0 V. However, the recommended operating range is 1.5 V to 5.5 V. Exceeding 5.5 V may trigger overvoltage stress even if within absolute ratings, and sustained operation above this limit risks reliability degradation per Toshiba's derating guidelines. Always verify VIN stays within 1.5–5.5 V in actual TCR2EE29,LM(CT) applications.

Does TCR2EE29,LM(CT) require an external pull-down resistor on the CONTROL pin?

No - TCR2EE29,LM(CT) integrates an internal pull-down between CONTROL and GND, ensuring reliable OFF-state behavior when the pin is left unconnected or driven high-impedance. External pull-downs are unnecessary and may interfere with active control. The CONTROL pin accepts 0–0.4 V for OFF and 1.0–5.5 V for ON, and its behavior is fully defined in the TCR2EE29,LM(CT) datasheet electrical characteristics table.

Can TCR2EE29,LM(CT) operate with a 0.47 μF output capacitor?

No - TCR2EE29,LM(CT) requires a minimum output capacitance of 1.0 μF, as specified in its operating ranges table. Using 0.47 μF violates the stability condition and may cause oscillation or excessive load transient deviation. Ceramic capacitors are supported, but must meet both value (≥1.0 μF) and ESR (<10 Ω) requirements. Always validate loop stability with 1.0 μF or higher in any TCR2EE29,LM(CT) design.

What is the thermal resistance (θJA) of TCR2EE29,LM(CT) in its ESV package?

TCR2EE29,LM(CT) does not specify θJA directly, but provides board-mounted power dissipation ratings: 320 mW on a 30 mm × 30 mm × 0.8 mm FR4 board with 20 mm² copper area. From this, θJA is approximately 219 °C/W (calculated as (150°C − 25°C) / 0.32 W). This value assumes optimal PCB layout - reduced copper area or smaller board dimensions will increase θJA and reduce safe power handling. Thermal design must reference the TCR2EE29,LM(CT) PD–Ta curve.

Is TCR2EE29,LM(CT) compliant with RoHS and REACH regulations?

Yes - TCR2EE29,LM(CT) is RoHS-compliant and meets EU REACH SVHC requirements, as confirmed by Toshiba's official environmental compliance documentation. It is lead-free, halogen-free, and manufactured using processes aligned with JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life. Full material declarations and test reports for TCR2EE29,LM(CT) are available through Toshiba's environmental portal or authorized distributors.
