Detailed Description
The MAX6023 precision bandgap references use a
proprietary curvature correction circuit and laser-
trimmed thin-film resistor, resulting in a low temperature
coefficient of <30ppm/
°
C and initial accuracy of better
than 0.2%. These devices can sink and source up to
500μA with <200mV of dropout voltage, making them
attractive for use in low-voltage applications.
Applications Information
Output/Load Capacitance
The MAX6023 devices do not require an output capaci-
tor for dynamically stable, oscillation-free operation.
They are stable for capacitive loads from 0 to 2.2nF.
However, in applications where the load or the supply
can experience step changes, an output capacitor
reduces the amount of overshoot (or undershoot) and
improves the circuit
’
s transient response. Many appli-
cations do not need an external capacitor and this fam-
ily offers a significant advantage in these applications
when board space is critical.
Supply Current
The no-load supply current of these series-mode refer-
ences is 35μA maximum, and is virtually independent
of the supply voltage, with only a 0.8μA/V variation from
the supply voltage. Unlike shunt-mode references that
must draw the maximum load current at all times, the
load current is drawn from the input voltage source only
when required, so supply current is not wasted and effi-
ciency is maximized at all input voltages. This improved
efficiency can help reduce power dissipation and
extend battery life.
When the supply voltage is below the minimum speci-
fied input voltage (as during turn-on), the devices can
draw up to 200μA beyond the nominal supply current.
The input voltage source must be capable of providing
this current to ensure reliable turn-on.
Output Voltage Hysteresis
Output voltage hysteresis is the change in the output
voltage at T
A
= +25
°
C before and after the device is
cycled over its entire operating temperature range.
Hysteresis is caused by differential package stress
appearing across the bandgap core transistors. The
typical temperature hysteresis value is 90ppm.
Turn-On Time
These devices typically turn on and settle within 0.1%
of their final value; 30μs to 220μs depending on the
device. The turn-on time can increase up to 1.5ms with
the device operating at the minimum dropout voltage
and the maximum load.
UCSP Information
UCSP Package Consideration
For general UCSP package information and PC layout
considerations, refer to the Maxim Application Note:
UCSP
—
A Wafer-Level Chip-Scale Package.
UCSP Reliability
The UCSP represents a unique package that greatly
reduces board space compared to other packages.
The chip-scale package represents a unique packag-
ing form factor that may not perform as well as a pack-
aged product through traditional mechanical reliability
tests. UCSP reliability is integrally linked to the user
’
s
assembly methods, circuit board material, and usage
environment. The user should closely review these
areas when considering use of a chip-scale package.
Performance through operating-life test and moisture
resistance remains uncompromised. The wafer-fabrica-
tion process primarily determines the performance.
Mechanical stress performance is a greater considera-
tion for chip-scale packages. Chip-scale packages are
attached through direct solder contact to the user
’
s PC
board, foregoing the inherent stress relief of a pack-
aged product lead frame. Solder joint contact integrity
must be considered. Comprehensive reliability tests
have been performed and are available upon request.
In conclusion, the UCSP performs reliably through envi-
ronmental stresses.
