Description
Supply Voltage Input for LDO1 and LDO2. Connect IN2 to a battery or
supply voltage from 2.7V to 5.5V. Decouple IN2 with a 1 μ F ceramic
capacitor as close as possible to IN2 and AGND. Connect IN2 to the same
source as IN1A and IN1B.
NC. Used for internal test purpose. The pin is internally pulled down with a
110k Ω resistor.
Supply Voltage Input for PA Step-Down Converter. Connect IN1A/B to a
battery or supply voltage from 2.7V to 5.5V. Decouple IN1A/B with a 10 μ F
ceramic capacitor as close as possible to IN1A/B, and PGND. IN1A and
IN1B are internally connected together. Connect IN1A/B to the same source
as IN2.
10mA LDO Regulator 1 Output. Decouple LDO1 with a 0.1 μ F ceramic
capacitor as close as possible to LDO1 and AGND. LDO1 is internally pulled
down through a 100 Ω resistor when this regulator is disabled.
Enable Input for LDO1. For normal operation, connect to logic-high. For
shutdown mode, connect to logic-low. The pin is internally pulled down
through a 110k Ω resistor.
PA Connection for Bypass Mode. Internally connected to IN1A/B using
the internal bypass MOSFET during bypass mode. Connect PAA/B with a
4.7 μ F ceramic capacitor as close as possible to PAA/B and PGND.
