RP105x Series
400mA 0.9V Input LDO with dual input pin
No.EK-179-100119
CMOS LDO Regulator
The RP105x Series are CMOS-based LDO regulators featuring 400mA output with dual input pin. The input voltage can correspond
from 0.9V by the inputting voltage into VBIAS. The UVLO function will lock out the internal circuit, if the input voltage is less than the
UVLO voltage. Due to a built-in Nch. transistor with low on-resistance of 0.4
Ω (at VOUT=0.8V), RP105x provides a low dropout voltage.
RP105x also has an excellent line transient response. In addition to SOT-23-5 and SC-88A packages, a 1.2mm square DFN(PLP)1212-6
package is also available.
