Designed with portable applications in mind, the ADP120, ADP121 and ADP130 low dropout linear regulators (LDOs) from Analog Devices offer low-noise performance in combination with low quiescent current and chip-scale packaging. These LDOs offer single outputs of 100 mA or 150 mA, or a dual output of 350 mA.
Device type: single and dual low-dropout regulators
Output voltage: single output at 1.2 V to 3.3 V (ADP120, ADP121), dual output at 0.80 V to 3.0 V (ADP130)
Output current: 100 mA (ADP120), 150 mA (ADP121), 350 mA (ADP130)
Output voltage accuracy: ±1% (initial accuracy, all devices)
Quiescent current(no load): 11 μA (ADP120, ADP121) or 25 μA (ADP130)
Features: stable with 1-μF ceramic output capacitor (all three devices), 60-mV dropout voltage at 100 mA (ADP120, ADP121) or 17-mV dropout at 100 mA (ADP130), 60 dB PSRR at 10 kHz (ADP120, ADP121), 40-μV rms noise figure (ADP120 and ADP121)
Operating temperature range (TJ): -40°C to 125°C
Packaging: 5-lead TSOP (all devices); 0.86 mm × 0.86 mm, 4-ball WCSP (ADP120 and ADP121)
RoHS compliant? yes
Target applications: battery-powered devices such as portable audio players, digital still cameras, handheld games and personal navigation systems
Pricing: ranges from $0.26 to $0.33 each in quantities of 1000 for the TSOT package; contact the vendor for WLCSP pricing
Availability: available now
Data sheet posted on web? yes, see http://www.analog.com/static/imported-files/data_sheets/ADP120.pdf
Notes: The dual-output ADP130 can be biased from a higher input supply, while the load current is sourced from a lower input supply to reduce overall power dissipation and enable low dropout operation.
