Description
The R1160D151B-TR is a CMOS-based voltage regulator IC with high output voltage accuracy, low supply current, and low ON-resistance, belonging to the R1160x Series. This voltage regulator IC consists of a voltage reference unit, an error amplifier, resistors for setting Output Voltage, a current limit circuit, and a chip enable circuit. The IC performs with low dropout voltage and a chip enable function. It also includes a current limit circuit to prevent destruction in the case of overcurrent. The R1160x Series comes with 3 modes. One is standby mode with CE or standby control pin, and the other two modes are realized with ECO pin. Fast Transient Mode (FT mode) and Low Power Mode (LP mode) are alternate modes that are activated with the ECO pin™. Consumption current is reduced to 1/10 at Low Power Mode compared with Fast Transient Mode, and output voltage is maintained between FT mode and LP mode. The ultra-low supply current and high output voltage accuracy, along with a built-in fold-back protection circuit make this voltage regulator IC ideal for precise voltage references, power source for electrical appliances such as cameras, VCRs and hand-held communication equipment, and power source for battery-powered equipment.
