Package
■General Description
The XC62K series are highly precise, low power consumption, negative
voltage regulators, manufactured using CMOS and laser trimming
technologies. The series achieves high output currents with small input-
output voltage differentials, and consists of a high precision voltage
reference, an error correction circuit, and an output driver with current
limitation.
SOT-23 (150mW), SOT-89 (500mW) and TO-92 (300mW) packages are
available.
■Features
Ultra Small Input-Output Voltage Differential
: 50mA output possible with a 0.12V
differential (V
OUT
=-5.0V).
Maximum Output Current
: 100mA (within max. power
dissipation, V
OUT
= -5.0V)
Output Voltage Range
: -2.1V ~ -6.0V in 0.1V increments.
-5.0, -4.0, -3.0V, -2.5V standard.
(All other voltages are semi-custom)
Highly Accurate
: Output voltage ±2%
(±1% for semi-custom products)
Low Power Consumption
: Typ. 3.0µA @ V
OUT
= -5.0V
Output Voltage Temperature Characteristics
: Typ. ±100ppm/°C
Input Stability
: Typ. 0.1%/V
Ultra Small Packages
: SOT- 23 (150mW) mini-mold,
SOT-89 (500mW) mini-power mold
TO-92 (300mW)
