FUNCTIONAL PIN DESCRIPTION
PIN NAME
PIN #
DESCRIPTION
VOUT
1
Regulated Output Voltage. It is recommended to bypass VOUT with a low ESR capacitor (> 2F) placed as close
to the pin as possible for best performance. For the adjustable version, the output voltage range is 2.5V to 5.5V.
SHDN
2
Shutdown Pin. The LX1882 is in shutdown mode when a logic low is applied to this pin. Inversely, a logic high
applied to this pin enables the device. When in shutdown mode, the charge pump output is disconnected from VIN
(CPO will be high impedance) and VOUT is connected to ground through an internal 100 switch.
FB
3
Adjustable Version Only. The output voltage can be set by two resistors with the following relationship: VOUT =
FB * (1+ (R1/R2)) where R1 is the resistor connected between VOUT and FB, and R2 is the resistor connected
between FB and GND (see figure 3 on page 6).
FILT
3
Fixed Version Only. Filter pin for internal voltage reference. Typically a 1nF capacitor is connected from FILT to
GND.
GND
4
System Ground.
C-
5
Flying Capacitor Negative Input.
VIN
Input Voltage. The input voltage range is 1.8V to 4.4V for the LX1882-00 and 2V to 4.4V for the LX1882-33.
VIN should be bypassed with a > 2F low ESR capacitor placed as close to the pin as possible for best
performance. A minimum capacitance value of 0.1F is required.
C+
7
Flying Capacitor Positive Input.
CPO
8
Charge Pump Output Voltage. CPO is approximately 1.95(VIN) at low loads. CPO should be bypassed with a low
ESR capacitor (>2F).
