250mA Low- Quiescent Current Linear Regulator
EC6209
Features
General Description
z 2.0µA Quiescent Current (Typ.)
The EC6209 series is a positive voltage regulator
with highly accurate output voltage and ultra-low
z Operating Voltages Rangej+1.8V to +6.0V ^{quiescent current which is typically 2.0µA. The}
device is ideal for battery powered applications and
z Output Voltages Rangej+1.2V to +5.0V with _{handheld communication equipments which require}
100mV Increment
low quiescent current.
z Maximum Output Currentj250 mA
z Low Dropout: 150 mV @ 100mA
(V_OUTÚ2.0 V)
z High Accuracy of Output Voltage
±2.0% : V_OUTÚ2.5 V
±50mV : V_OUTÙ2.5 V
z High Ripple Rejectionj60 dB
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)
z Output Current Limit Protection (350mA)
z Short Circuit Protection (200mA)
z Thermal Overload Shutdown Protection
z Low ESR Capacitor Compatible
z SOT-23, SOT-89 and UDFN-6 Packages
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.
z RoHS Compliant and 100% Lead (Pb)-Free
and Green (Halogen Free with Commercial
Standard)
Applications
z DSCePDAeMP3 Player
z Digital Video Recorder
z Battery Powered Instrument
z Portable Communication Device
