Design of a Low-Noise, Fast Set-up and Low-Voltage Low-Dropout Regulator Featuring 230mA Load Current Range
View through CrossRef
Low noise, high PSRR and fast transient
low-dropout (LDO) regulators are critical for analog blocks such as ADCs, PLLs
and RF SOC, etc. This paper presents design of low power, fast transient, high PSRR
and high load-regulation low-dropout (LDO) regulator. The proposed LDO
regulator is designed in 180nm. CMOS process and simulated in LTSpice and
Cadence platform. The LDO proposed can support input voltage range up to 5V for
loading currents up to 230mA. Measurements showed transient time or set-up time
of less than 22µs, PSRR of ~66dB at 100kHz and >40dB at 1MHz and 0.8535mV of
output voltage variation for a 0-230mA of load variation.
