). The power dissipation at
+70°C ambient is 571mW (see Absolute Maximum
Ratings). The thermal resistance junction-to-case of the
SOT23-5 package is 81°C/W, and the maximum safe
junction temperature is +150°C.
The GND pin performs the dual function of providing an
electrical connection to ground and channeling heat
away. Connect GND to ground using a large pad or
ground plane.
__________Applic ations Information
S etting the MAX 1616 Output V oltage
Set the MAX1616’s output voltage with two resistors, R1
and R2 (Figure 2). Choose R2 = 250k
to maintain a
5μA minimum load and calculate R1 using the following
equation:
where V
FBT
= 1.24V (typical).
Capac itor S elec tion
Use a 0.1μF minimum capacitor on the input. Higher
values will improve line-transient response.
Use 1μF minimum on the output, or 4.7μF for the full
30mA load current (6.8μF, MAX1616). Otherwise, use
1μF plus 0.125μF/mA (0.2μF/μA, MAX1616). For output
voltages less than 3.3V, use 15μF instead of 6.8μF. The
output capacitor’s effective series resistance (ESR) must
be less than 1
for stable operation.
Output V oltage Noise
The MAX1615/MAX1616 typically exhibit 5mVp-p of
noise during normal operation. This is negligible in
most applications. In applications that include analog-
to-digital converters (ADCs) of more than 12 bits, con-
sider the ADC’s power-supply-rejection specifications.
T ransient Response
The Typical Operating Characteristics show the
MAX1615/MAX1616’s load-transient response. Two of
the output response’s components can be observed on
the load-transient graph: a DC shift from the output
impedance due to the different load currents, and the
transient response. Typical step changes in the load
current from 10mA to 20mA produce 50mV transients.
Increasing the output capacitor’s value attenuates tran-
sient spikes.
