TOSHIBA TCR5AM105,LF

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 lOUT = 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×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.
