This paper proposes a low dropout voltage regulator (LDO) that exhibits both a fast response to load transients and the ability to handle practically any load capacitor. Starting from a typical LDO topology, an error amplifier (EA) that drives a PMOS

This article proposes an LDO with fast response to load transients that can handle any practical capacitive loads. These features are mainly due to a novel frequency compensation circuit tailored for its error amplifier, which is based on an improved

ICs designed for automotive applications should withstand accidental reverse polarity caused by misconnection of their supply lines to the car battery. The reverse protection circuitry should avoid damages to both the IC and the system the IC is conn

This paper presents an intuitive analysis of a class of conditionally stable feedback circuits, that are stable although the Bode stability criteria indicates otherwise: at the frequencies their loop gain phase characteristics first reach -180°, the

The metallization of double-diffused metal-oxide semiconductor (DMOS) power devices, which operate under fast thermal cycling (FTC), undergoes thermal induced plastic metal deformation (TPMD). The design of the metallization has a significant impact

This paper presents a methodology for designing over-temperature and over-current protection (OTP and OCP) circuits for low drop-out voltage regulators (LDOs). The OTP monitors the die temperature developed within the LDO and disables its output stag

This paper presents several design options for implementing a thermal shutdown circuit with hysteretic characteristic, which has two special features: a programmable activation temperature (the upper trip point of the characteristic) and a hysteresis

This paper presents an over-temperature protection (OTP) circuit for a DC-DC converter based on switching capacitors (SC DC-DC). The circuit was designed by using a two-step approach that encompasses running both electrical and electro-thermal simula

This paper presents a novel circuit implementation for overcurrent protection of low-dropout voltage regulators, that is able to limit the maximum current the regulator can source into the load to a value set by the user and to keep the current limit
