Description
RE023 is a Low Drop Out (LDO) voltage regulator macrocell with a fixed 2.6V output
voltage, rated for loads up to 160 mA. It is designed to be integrated with other analog
cells, digital logic, microcontrollers, DSP cores and memory 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 (bandgap voltage) is necessary for correct functionality.
The target reference voltage is 1.231V, delivered, for example, by BG019. Double
pads on the supply voltage V

provides regulation at the load by connecting it to the
output terminal near a critical point to improve performance of the regulator (e.g., con-
necting them at the package pin by double-bonding, thus avoiding the bonding
resistance influence). A ceramic capacitor of 2.2 μF connected from V
