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 IOUT = 500 mA (1.1 V output, VBIAS = 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.
