Description
RE028 is a Low Drop Out (LDO) voltage regulator macrocell with a fixed 4.5V output
voltage, rated for loads up to 30 mA. It is designed to be integrated with other analog
cells, digital logic, microcontrollers, DSP cores and memory blocks into system-on-
chip products. Furthermore, the RE028 is designed to supply radio frequency synthe-
sizers and used as a controller for the antenna switch.
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 (bandgap voltage) is necessary for correct functionality.
The target reference voltage is 1.231V, delivered, for example, by BG019. Current ref-
erence is generated inside the cell through a circuit supplied by a 2.5V ± 0.1V
regulated input voltage on V
SAUVC
. Remote sense terminal V
RADS
provides regulation
at the load by connecting it to the output terminal near a critical point to improve per-
formance of the regulator (e.g., connecting them at the package pin by double-
bonding, thus avoiding the bonding resistance influence). A ceramic capacitor of 2.2
μF connected from V
RAD
to ground is needed as external compensation.
