Description
RE029 is a dual mode Low Drop Out (LDO) voltage regulator macrocell with a fixed
1.8V output voltage, rated for loads up to 80 mA in full power mode and 5 mA in low
power mode. (Both modes can be selected by the LP8 signal.) It is designed to be
integrated with other analog cells, digital logic, microcontrollers, DSP cores and mem-
ory blocks into system-on-chip products.
The circuit consists of a PMOS pass device, an error amplifier and a feedback resis-
tive network, sized to achieve the required closed loop gain. These blocks make up
the regulating loop. An over-current and short circuit protection circuit has been
included to limit the output current delivered by the regulator, thus avoiding destruction
in case of a short circuit.
An external reference voltage V
BG
(bandgap voltage) is necessary for correct function-
ality. The target reference voltage is 1.231V delivered, for example, by BG019. Double
pads on the supply voltage V

and output voltage V

are used to
reduce the total output resistance. Current reference is generated inside the cell
through a circuit supplied by a 2.5V ± 0.1V of regulated input voltage on V
SAUVC
.
Remote sense terminal V
MLVS
provides regulation of the load by connecting it to the
output terminal near a critical point to improve performance of the regulator (e.g., con-
necting it to the package pin by double-bonding, thus avoiding the bonding resistance
influence). A ceramic capacitor of 2.2 μF connected from V

needed as external compensation.
