TCR5BM series

TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic

TCR5BM series

500 mA CMOS Ultra Low Dropout Regulator

1. Description

The TCR5BM series are CMOS single-output voltage regulators with an on/off

control input, featuring ultra low dropout voltage, high PSRR, low inrush current

and fast load transient response.

A differentiating feature is the use of a secondary bias rail as a reference

voltage that allows ultra low dropout of 100 mV (Typ.) at I_OUT= 500 mA (1.1 V

output, V_BIAS= 3.3 V).

These voltage regulators are available in fixed output voltages between 0.8 V

and 3.6 V, and capable of driving up to 500 mA. Other features include

overcurrent protection, thermal shutdown, and Auto-discharge.

The TCR5BM series are offered in the ultra small plastic mold package

DFN5B (1.2 mm x 1.2 mm; t 0.38 mm).

As small ceramic input and output capacitors can be used with the TCR5BM

series, these devices are ideal for portable applications that require high-density

board assembly such as cellular phones.
