500mA CMOS Ultra Low Drop-Out Regulator
Description
TCR5AM series
TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic
TCR5AM series
500 mA CMOS Ultra Low Drop-Out Regulator
The TCR5AM series are CMOS single-output voltage regulators with an on/off control input, featuring Ultra low dropout voltage, 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 drop-out of 90 mV (Typ.
) at IOUT = 300 mA ( 1.
1 V output, VBAT = 3.
3 V ).
These voltage regulators are available in fixed output voltages between 0.
55 V and 3.
6 V, and capable of driving up to 500 mA.
Other features include over-current protection, over-temperature protection, Under-voltage-lockout and Auto-discharge function.
The TCR5AM 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 TCR5AM series, these devices are ideal for portable applications that require high-density board assembly such as cellular phones.
