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.

Note:
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).
