LDO Linear Regulators

Analog Devices offers a broad line of high performance, low dropout linear regulators

Image of Analog Devices' LDO Linear RegulatorsAnalog Devices manufactures a broad line of high performance low dropout (LDO) linear regulators with fast transient response, excellent line and load regulation, and very wide input voltage range from 0.9 V to 100 V. Output currents range from 20 mA to 10 A with positive, negative, and multiple output versions available. Many devices offer output voltage operation less than 0.8 V and some feature operation as low as 0 V, even with a single supply. Most are stable with ceramic output capacitors. LDO regulators can be applied in virtually any application.

  • Second generation NPN family features:
    • Operation down to 0 V output
    • Direct paralleling to spread PCB heat
    • Low noise and simplicity with a single resistor VOUT set capability
Positive LDOs
  • Positive linear regulators family features:
    • Low output voltage noise
    • Fast transient response
    • Extensive reverse protection
    • Very low dropout voltage
Dual Positive and Negative LDOs
  • Dual linear regulator family features:
    • Highly compact solution
    • All the performance features of Analog Devices' single PNP regulators
    • Ideal for core / logic combinations
Negative LDOs
  • Rugged and hard to kill negative linear regulator family features:
    • Low output voltage noise
    • Wide voltage range
    • Low dropout voltage
    • Extensive reverse protection
