The device is ideal for battery powered applications and handheld communication equipments which require low quiescent current. The EC6209 consists of a band-gap reference voltage source, an error amplifier, a P-channel pass transistor, a resistor-divider for setting output voltage, a current limiter, and temperature limit protection circuit. The high-accuracy output voltage is preset at an internally trimmed voltage 1.8V, 2.5V or 3.3V. Other output voltages can be mask- optioned from 1.2V to 5.0V with 100mV increment. (but only 1.28V in stead of 1.3V) The EC6209 has been designed to be used with low cost ceramic capacitors and requires a mini- mum output capacitor of 1.0µF. The devices are available in SOT-23, SOT-89, and UDFN-6 pack- ages.

250mA Low- Quiescent Current Linear Regulator EC6209 ECMOS CO. ( http://www.ecmos.com.tw) TEL : 886-3-5785888 FAX : 886-3-5783630 P 7 / 24 2009/04/28 Detail Description The EC6209 is a low quiescent current LDO linear regulator. The device provi des preset 1.8V, 2.5V and 3.3V output voltages for output current up to 350mA. Other mask options for special output voltages from 1.2V to 5.0V with 100mV increment are also available (but only 1.28V in stead of 1.3V). As illustrated in function block diagram, it consists of a 1.23V reference, error amplifier, a P-channel pass transistor, and an internal feedback voltage divider. The 1.23V band-gap reference is connected to the error amplifier, which compares this reference with the feedback voltage and amplifies the voltage difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled l o w e r , w h i c h a l l o w s m o r e c u r r e n t t o p a s s t o t h e output pin and increases the output voltage. If the feedback voltage is too high, the pass-transistor gate is pulled up to decrease the output voltage. The output voltage is feedback through an internal resistive divider connected to V OUT pin. Additional blocks include with output current limiter and shutdown logic. Internal P-channel Pass Transistor The EC6209 features a P-channel MOSFET pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFET require no base drive, which reduces quiescent current. PNP– based regulators also waste considerable current in dropout conditions when the pass transistor saturates, and use high base-drive currents under large loads. The EC6209 does not suffer from these problems and consumes only 2.0µA (Typical) of current consumption under light loads. Output Voltage Selection The EC6209 output voltage is preset at an intern- ally trimmed voltage 1.8V, 2.5V or 3.3V. The output voltage also can be mask-optioned from 1.2V to 5.0V with 100mV increment by special order (but only 1.28V in stead of 1.3V). The first two digits of part number suffix identif y the output voltage (see ). For example, EC6209- 33 has a preset 3.3V output voltage. Current Limit The EC6209 also includes a fold back current limiter. It monitors and controls the pass-transis- tor’s gate voltage, estimates the output current, and limits the output current within 350mA. Thermal Overload Protection Thermal overload protection limits total power dissipation in the EC6209. When the junction temperature exceeds T J = +155°C , a thermal sensor turns off the pass transistor, allowing the IC to cool down. The thermal sensor turns the pass transistor active again after the junction temperature cools down by 10°C , resulting in a pulsed output during continuous thermal overload conditions. Thermal overload protection is designed to protect the EC6209 in the event of fault conditions. For continuous operation, the maximum operating junction temperature rating of T J=+125°C should not be exceeded. Dropout Voltage A regulator’s minimum input-output voltage differential, or dropout voltage, determines the lowest us- able supply voltage. In battery-powered systems, this will determi ne the useful end-of-life battery voltage. The EC6209 uses a P-channel MOSFET pass transistor, its dropout voltage is a function of drain-to-source on-resistance (R DS(ON)) multiplied by the load current. () OUTONDSOUTINDROPOUT IRVVV ×=−=
