Product data sheet
Input option
Internal regulator
Regulator bypass connected to VREG3V3 with
Power supply input options
7.4 Power supply input options
V
supply input for internal regulator
(4.0 V to 5.5 V)
maximum voltage drop of 0.3 V
(2.7 V to 3.6 V)
CC(5V0)
The ISP1102A has two power supply input options.
Internal regulator — Pin V
used to supply the internal circuitry with 3.3 V (nominal). The VREG3V3 pin becomes a
3.3 V output reference.
Regulator bypass — Pins V
The internal regulator is bypassed and the internal circuitry is supplied directly from
pin VREG3V3. The voltage range is 3.0 V to 3.6 V to comply with
Bus Specification Rev.
The supply voltage range for each input option is specified in
Rev. 01 — 15 February 2007
2.0”.
VREG3V3
