APPLICATIONS VCOs RF Bluetooth, Wireless LAN
DESCRIPTIONThe TPS791xx family of low-dropout (LDO)
low-power linear voltage regulators features high
power supply rejection ratio (PSRR), ultralow
noise, fast start-up, and excellent line and load
transient responses in a small outline, SOT23,
package. Each device in the family is stable with
a small 1-µF ceramic capacitor on the output.
The family uses an advanced, proprietary
BiCMOS fabrication process to yield extremely
low dropout voltages (e.g., 38 mV at 100 mA,
TPS79147). Each device achieves fast start-up
times (approximately 63 µs with a 0.001 µF
bypass capacitor) while consuming very low
quiescent current (170 µA typical). Moreover,
when the device is placed in standby mode, the
supply current is reduced to less than 1 µA. The
TPS79118 exhibits approximately 15 µVRMS of
output voltage noise with a 0.1 µF bypass
capacitor.
Applications with analog components that are
noise sensitive, such as portable RF electronics,
benefit from the high PSRR and low noise
features as well as the fast response time.
ORDERING INFORMATION(1) The DBVR indicates tape and reel of 3000 parts.
(2) This part is Product Preview.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
