design ideas Dual 500mA ВµPower LDO Features Independent 1.8VвЂ“20V
Inputs and Easy Sequencing in a 4mm Г— 3mm DFN
Molly Zhu The LT3029 integrates
two independent 500mA
monolithic LDOs in a
tiny 16-lead MSOP or
4mm Г— 3mm Г— 0.75mm DFN
package. Both regulators
have a wide 1.8V to 20V
input voltage range with
a 300mV dropout voltage
at full load. The output
voltage is adjustable down
to the 1.215V reference
voltage. With an external
bypass capacitor, the
output voltage noise is less
than 20ВµVRMS. A complete
power supply requires only
a minimum 3.3ВµF ceramic
output capacitor for each
channel to be stable.
Quiescent current is 55ВµA per channel, dropping below 1ВµA in shutdown. …
