I. Device Description
A. General
The MAX6100 is a low-cost, low-dropout (LDO), micropower voltage references. This three-terminal reference has an
output voltage option of 1.8V. It features a proprietary curvature-correction circuit and laser-trimmed, thin-film
resistors that result in a low temperature coefficient of 75ppm/C (max) and an initial accuracy of 0.4% (max). This
device is specified over the extended temperature range (-40C to +85C).
This series-mode voltage reference draws only 90A of supply current and can source 5mA and sink 2mA of load
current. Unlike conventional shunt-mode (two-terminal) references that waste supply current and require an external
resistor, this device offers a supply current that is virtually independent of the supply voltage (with only a 4A/V
variation with supply voltage) and does not require an external resistor. Additionally, this internally compensated
device does not require an external compensation capacitor and is stable with load capacitance. Eliminating the
external compensation capacitor saves valuable board area in space-critical applications. Low dropout voltage and
supply-independent, ultra-low supply current makes this device ideal for battery-operated, high-performance, low-
voltage systems.
The MAX6100 is available in a tiny 3-pin SOT23 packages.

VI. Reliability Evaluation
A. Accelerated Life Test
The results of the 135
C biased (static) life test are shown in Table 1. Using these results, the Failure
Rate (
) is calculated as follows:
= 1 = 1.83 (Chi square value for MTTF upper limit)
MTTF
192 x 4389 x 160 x 2
Temperature Acceleration factor assuming an activation energy of 0.8eV
= 6.79 x 10
-9
= 6.79 F.I.T. (60% confidence level @ 25
C)
This low failure rate represents data collected from Maxim's reliability monitor program. In addition to
routine production Burn-In, Maxim pulls a sample from every fabrication process three times per week and subjects
it to an extended Burn-In prior to shipment to ensure its reliability. The reliability control level for each lot to be
shipped as standard product is 59 F.I.T. at a 60% confidence level, which equates to 3 failures in an 80 piece
sample. Maxim performs failure analysis on any lot that exceeds this reliability control level. Attached Burn-In
Schematic (Spec. # 06-5630) shows the static Burn-In circuit. Maxim also performs quarterly 1000 hour life test
monitors. This data is published in the Product Reliability Report (RR-1M).
B. Moisture Resistance Tests
Maxim pulls pressure pot samples from every assembly process three times per week. Each lot sample
must meet an LTPD = 20 or less before shipment as standard product. Additionally, the industry standard
85
C/85%RH testing is done per generic device/package family once a quarter.
C. E.S.D. and Latch-Up Testing
The RF24-7
die type has been found to have all pins able to withstand a transient pulse of
1500V, per Mil-
Std-883 Method 3015 (reference attached ESD Test Circuit). Latch-Up testing has shown that this device
withstands a current of
250mA.
