Toshiba Semiconductor and Storage TCR2EE13,LM(CT

Overview

TCR2EE13,LM(CT from Toshiba Electronic Devices & Storage Corporation is a 1.3 V fixed-output, 200 mA CMOS low dropout regulator with fast load transient response (±60 mV), low dropout voltage (350 mV typ. at 150 mA), and low output noise (35 μVrms typ. at 2.5 V). It features on/off control input, auto-discharge, overcurrent protection, and operates from −40°C to +85°C - ideal for powering analog sensor front-ends and RF bias rails in compact portable devices.

For engineers reviewing the TCR2EE13,LM(CT) datasheet, TCR2EE13,LM(CT) pinout, TCR2EE13,LM(CT) application, or TCR2EE13,LM(CT) equivalent, key selection criteria include dropout performance at 1.3 V output, ceramic capacitor compatibility (CIN ≥ 0.1 μF, COUT ≥ 1.0 μF), control logic thresholds (VCT(OFF) ≤ 0.4 V), thermal derating on small PCBs, and ±1.0% output accuracy for precision analog supply rails.

Technical Context

The TCR2EE13,LM(CT) implements a CMOS-based LDO architecture with integrated P-channel pass transistor, enabling ultra-low quiescent current (35 μA typ.) and stable regulation under rapid load steps (1 mA ↔ 150 mA). Its internal reference and error amplifier are optimized for high PSRR (73 dB typ. at 1 kHz) and minimal temperature drift (100 ppm/°C).

It supports active discharge via internal pull-down on VOUT when CONTROL = LOW, and requires no external compensation due to inherent stability with 1.0 μF ceramic output capacitance. The device operates within 1.5–5.5 V input range and tolerates up to 6.0 V absolute maximum VIN.

FAQ

What is the maximum input voltage for TCR2EE13,LM(CT)?

The absolute maximum input voltage for TCR2EE13,LM(CT) is 6.0 V. However, the recommended operating input voltage range is 1.5 V to 5.5 V. Exceeding 5.5 V may trigger overvoltage stress not covered by warranty, and sustained operation above this limit risks junction overheating even within thermal limits - always refer to the Absolute Maximum Ratings table in the official Toshiba datasheet for TCR2EE13,LM(CT).

Does TCR2EE13,LM(CT) require an external resistor network for output voltage setting?

No, TCR2EE13,LM(CT) is a fixed-output LDO with factory-trimmed 1.3 V regulation - no external resistors are needed or supported. Its output voltage is laser-trimmed during production and specified as ±18 mV (±1.38%) for VOUT < 1.8 V. Adding external components to adjust voltage will disrupt internal feedback and void regulation guarantees for TCR2EE13,LM(CT).

Can TCR2EE13,LM(CT) be used with 0.47 μF output capacitance?

No - TCR2EE13,LM(CT) requires a minimum output capacitance of 1.0 μF ceramic (ESR < 10 Ω) for guaranteed stability and specified transient performance. Using 0.47 μF violates the design condition for ±60 mV load transient response and may cause oscillation or excessive overshoot; Toshiba explicitly specifies COUT ≥ 1.0 μF in the Operating Ranges table for TCR2EE13,LM(CT).

What happens to VOUT when the CONTROL pin is left floating?

When the CONTROL pin of TCR2EE13,LM(CT) is left floating, it defaults to OFF state due to internal pull-down - resulting in VOUT being discharged to near 0 V. This behavior is confirmed in Toshiba's Application Note: "OPEN → OFF". To ensure reliable enablement, CONTROL must be actively driven to ≥1.0 V; floating is not a valid operational mode for TCR2EE13,LM(CT).

Is TCR2EE13,LM(CT) RoHS compliant and lead-free?

Yes, TCR2EE13,LM(CT) is RoHS compliant and lead-free, as confirmed by Toshiba's official product documentation and environmental compliance statements. The ESV (SOT-553) package uses lead-free matte tin plating, and the device meets EU RoHS Directive 2011/65/EU requirements - full material declarations and test reports are available through Toshiba's official website or authorized distributors for TCR2EE13,LM(CT).
