Negative Linear Regulators (LDO)
Analog Devices manufactures a broad line of high performance low dropout linear regulators. These LDOs offer very low dropout, a fast transient response, and excellent line and load regulation, and they have a very wide input voltage range—anywhere from 0.9 V to 80 V. Output currents range from 100 mA to 10 A, with negative outputs.
