DESCRIPSION
The TJ5205 is an efficient linear voltage regulator with ultra low-noise output, very low dropout voltage (typically
17mV at light loads and 165mV at 150mA), and very low ground current (600µA at 100mA output).
The TJ5205 offers better than 1% initial accuracy. Designed especially for hand-held, battery-powered devices,
the TJ5205 includes a CMOS or TTL compatible enable/shutdown control input. When shutdown, power
consumption drops nearly to zero.
Regulator ground current increases only slightly in dropout, further prolonging battery life.
Key TJ5205 features include a reference bypass pin to improve its already excellent low-noise performance,
reversed-battery protection, current limiting, and over temperature shutdown.
The TJ5205 is available in fixed and adjustable output voltage versions in SOT-23-5 PKG and SOP-8PP PKG.
And adjustable type’s maximum output voltage is 8.5V.
