6, 7
EN_LDO,
EN_CHIP
EN_LDO (pin 6) and EN_CHIP (pin 7) are active-high TTL-level logic inputs to enable the linear
regulator and charge pump according to the following truth table:
8VOUT
The regulated output. An output capacitor may be added to improve noise and load-transient
response. When the LDO regulator is disabled, an internal pull-down with a nominal resistance
of 500 ohms is activated to discharge the VOUT rail to GND
9, 10
CP+, CP-
CP+ (pin 9) and CP- (pin 10) are used to connect the external "flying" capacitor CP to the charge
pump. The charge stored in CP is transferred to the reservoir capacitor CS at the 250kHz inter-
nal clock rate.
