Toshiba TCR3RM Low Noise LDO Regulator

Toshiba TCR3RM Low Noise Low Dropout (LDO) Regulator achieves industry-leading ripple rejection and ultra-low output voltage noise, making it ideal for supplying power to sensitive ICs, chipsets, and other components which require stable supply. The TCR3RM is offered with output voltages from 0.9V to 4.5V, covering the most popular voltage ranges. The TCR3RM LDO Regulator also features a high 100dB (typical) Power Supply Rejection Ratio (PSRR). This enables the device to stabilize high-frequency noise, which comes from external environments or DC-DC converters and can cause malfunctions. Intrinsic output voltage noise has been minimized to just 5μVRMS, and the dropout voltage is just 130mV (typical) at a 2.8V, 300mA output.

The TCR3RM also features an extremely low quiescent current and low passive current consumption (7μA at IOUT = 0mA). This allows for longer operating times in battery-driven devices while supplying power to sensitive ICs and other components.

This Toshiba TCR3RM LDO Regulator is packaged in a low profile 1.0mm x 1.0mm x 0.38mm DFN4C package, allowing for high-density designs in mobile consumer-type products.
