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.

Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation at any TA (ambient temperature) is PD(max)=(TJ(max)–TA)+ θJA. Exceeding the maximum
allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The θJA of the
TJ5205-XX (all versions) is 220°C/W mounted on a PC board
The TJ5205-ADJ has VREF=1.242V±1%, but minimum output voltage for TJ5205-ADJ must be above VOUTmin=2.0V.
Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in
the load range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal regulation
specification.
Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured
at 1V differential.
Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is
the sum of the load current plus the ground pin current.
Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding
load or line regulation effects. Specifications are for a 150mA load pulse at VIN = 16V for t = 10ms.
