8.2
The PIC16F1526 device contains an internal Low
Dropout (LDO) voltage regulator, which allows the
device I/O pins to operate at voltages up to 5.5V while
the internal device logic operates at a lower voltage.
The LDO and its associated reference circuitry must
remain active when the device is in Sleep mode. The
PIC16F1526 allows the user to optimize the operating
current in Sleep, depending on the application require-
ments.
A Low-Power Sleep mode can be selected by setting
the VREGPM bit of the VREGCON register. With this
bit set, the LDO and reference circuitry are placed in a
low-power state when the device is in Sleep.
8.2.1
In the Default Operating mode, the LDO and reference
circuitry remain in the normal configuration while in
Sleep. The device is able to exit Sleep mode quickly
since all circuits remain active. In Low-Power Sleep
mode, when waking up from Sleep, an extra delay time
is required for these circuits to return to the normal con-
figuration and stabilize.
The Low-Power Sleep mode is beneficial for applica-
tions that stay in Sleep mode for long periods of time.
The normal mode is beneficial for applications that
need to wake from Sleep quickly and frequently.

Preliminary
8.2.2
Some peripherals that can operate in Sleep mode will
not operate properly with the Low-Power Sleep mode
selected. The LDO will remain in the normal power
mode when those peripherals are enabled. The
Low-Power Sleep mode is intended for use with these
peripherals:
• Brown-Out Reset (BOR)
• Watchdog Timer (WDT)
• External interrupt pin/Interrupt-on-change pins
• Timer1 (with external clock source)
• CCP (Capture mode)
Note:
PIC16(L)F1526/27
PERIPHERAL USAGE IN SLEEP
The PIC16LF1526/27 does not have a
configurable Low-Power Sleep mode.
PIC16LF1526/27 is an unregulated device
and is always in the lowest power state
when in Sleep, with no wake-up time pen-
alty. This device has a lower maximum V
and I/O voltage than the PIC16LF1526/27.
