LDK120
200 mA low quiescent current very low noise LDO
Datasheet - production data
Applications
• Mobile phones
• Personal digital assistants (PDAs)
627/
')1[PP
• Cordless phones and similar battery-powered
systems
• Digital still cameras
Description
The LDK120 low drop voltage regulator provides
200 mA of maximum current from an input supply
voltage in the range of 1.9 V to 5.5 V, with a
typical dropout voltage of 100 mV.
627/
It is stabilized with a ceramic capacitor on the
output.
Features
• Input voltage from 1.9 to 5.5 V
• Very low dropout voltage (100 mV typ. at 100
mA load)
• Low quiescent current (max. 100 µA, 1 µA in
OFF mode)
• Very low noise
• Output voltage tolerance: ± 2.0% @ 25 °C
The very low drop voltage, low quiescent current
and low noise features make it suitable for low
power battery-powered applications.
An enable logic control function puts the LDK120
in shutdown mode allowing a total current
consumption lower than 1 µA.
The device also includes a short-circuit constant
current limiting and thermal protection.
• 200 mA guaranteed output current
• Wide range of fixed output voltages available
on request: from 0.8 V to 3.5 V with 100 mV
step
• Adjustable version: from 0.8 V to VIN-Vdrop
• Logic-controlled electronic shutdown
• Compatible with ceramic capacitor COUT = 1 µF
• Internal current and thermal limit
• Available in SOT23-5L, SOT323-5L and DFN6
(1.2 x 1.3 mm) packages
• Temperature range: -40 °C to 125 °C
