TCR8BM series TOSHIBA CMOS Linear Integrated Circuit Silicon Monolithic TCR8BM series 800 mA CMOS Ultra Low Dropout Regulator The TCR8BM 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 170 mV (Typ.) at I = 800 mA ( 1.1 OUT V output, V = 3.3 V ). BIAS These voltage regulators are available in fixed output voltages between 0.8 V and 3.6 V, and capable of driving up to 800 mA. Other features include overcurrent protection, thermal shutdown, and Auto-discharge. The TCR8BM 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 DFN5B TCR8BM series, these devices are ideal for portable applications that require Weight : 1.4 mg ( Typ.) high-density board assembly such as cellular phones.

Exposure to such conditions may adversely impact product reliability and results in failures not covered by warranty. Maximum operating ranges output current specification defined as lifetime average junction temperature of +45C where max rated DC current = lifetime average current to avoid electro migration. 2018-2019 2019-01-15 2 Toshiba Electronic Devices & Storage Corporation
