HX9193
600mA,Ultra-low noise, Ultra-Fast CMOS LDO Regulator
General Description
The HX9193 is designed for portable RF and wireless
applications with demanding performance and space
requirements. The HX9193 performance is optimized
for battery-powered systems to deliver ultra low noise
and low quiescent current. Regulator ground current
increases only slightly in dropout, further prolonging
the battery life. The HX9193 also works with low-ESR
ceramic capacitors, reducing the amount of board
space necessary for power applications, critical in
hand-held wireless devices. The HX9193 consumes
less than 0.01µA in shutdown mode and has fast
turn-on time less than 20µs. The other features include
ultra low dropout voltage, high output accuracy,
current limiting protection, and high ripple rejection
ratio. It is available in the 5-lead of SOT23-5
packages.
