R1160x SERIES 3-MODE 200mA LDO REGULATOR is a low power, low dropout voltage, high accuracy LDO chip from ROHM, which has 3 working modes and can be switched between Fast Transient Mode (FT mode) and Low Power Mode (LP mode) by ECO pin.
The Ricoh R1160x Series consists of CMOS-based voltage regulator ICs designed with high output voltage accuracy, low supply current, and low ON-resistance. These ICs include a current limit circuit to prevent destruction by overcurrent and feature a chip enable function. They operate with low dropout voltage and offer three modes: Standby Mode, Fast Transient Mode (FT), and Low Power Mode (LP).
| Supply Current (Low Power Mode) | Typ. 3.5uA (Vout = 1.5V) |
|---|---|
| Output Voltage Range | 0.8V to 3.3V (0.1V steps) |
| Input Voltage Range | 1.4V to 6.0V |
| Short Current Limit | Typ. 50mA |
The series has three modes: Standby Mode, Fast Transient Mode (FT mode), and Low Power Mode (LP mode).
Consumption current is reduced to 1/10 in Low Power Mode compared with Fast Transient Mode, while output voltage is maintained between the two modes.
The ICs are available in SOT-23-5 and SON-6 packages.
