DESCRIPTION
The BL9193 is designed for portable RF and
wireless applications with demanding perfor-
mance and space requirements. The BL9193
performance is optimized for battery-powered
systems to deliver ultra low noise and low
quiescent current. A noise bypass pin is
available for further reduction of output noise.
Regulator ground current increases only
slightly in dropout, further prolonging the
battery life. The BL9193 also works with low-
ESR ceramic capacitors, reducing the
amount of board space necessary for power
applications, critical in hand-held
wireless
devices. The BL9193 consumes less than
0.01µA in shutdown mode and has fast turn-
on time less than 50µs. The other features
include ultra low dropout voltage, high output
accuracy, current limiting protection, and high
ripple rejection ratio. Available in the 5-lead of
SC-70, SOT-23 packages.
APPLICATIONS
Cellular and Smart Phones
Battery-Powered Equipment
Laptop, Palmtops,Notebook Computers

Note 1:
Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2:
The BL9193 is guaranteed to meet performance specifications from 0°C to 70°C. Specifications over the –40°C
to 85°C operating temperature range are assured by design, characterization and correlation with statistical
process controls.
Note 3:
Y: Year of manufacturing W: Week of manufacturing
Note 4:
Thermal Resistance is specified with approximately 1 square of 1 oz copper.
