PAM3106

PAM3106 300mA High PSRR Low Dropout CMOS Linear Regulator Features n Maximum Output Current: 300mA n Dropout Voltage:180mV @ I OUT =300mA and Vo=3.3V n Operating Voltage Range:2.7V to 5.5V n Standby Current: Less than 0.1uA (TYP.) n High Ripple Rejection: 80dB (1kHz) n Fast Start-Up n Quick Discharge O O n Operating Temperature Range:-40 C~+ 85 C n Low ESR Capacitor Compatible: Ceramic Capacitor n Ultra Small Packages: SOT23-5, SOT23-3 and WDFN-6L 1.6X1.6 package n Pb-Free Package General Description The PAM3106 series are precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The series achieves high ripple rejection and low dropout and consists of a voltage reference, an error amplifier, a current limiter and a phase compensation circuit plus a driver transistor. The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. Th e c u r r e n t l i m i te r 's f o l d b a c k c i r c u i t a l s o operates as a short protect for the output current limiter and the output pin. The EN function enables the output to be turned off, resulting in greatly reduced power consumption.
